White glove migration: A guide to fully managed replatforming (2026) – Shopify

Moving platforms? A white glove migration takes the weight of this complex process off your team’s shoulders. You let specialists handle the heavy lifting, and they take full accountability for the results.

For ecommerce brands, this matters even more. US retail ecommerce sales hit $1.19 trillion in 2024, according to the US Census Bureau. With stakes this high, a botched migration can mean lost revenue, damaged SEO rankings, and unhappy customers during key trading periods.

This guide explains what white glove migration is, what’s included and what isn’t, and shows how the process works step by step. This information can help you decide whether this is the right fit for your replatforming project.

What is a white glove migration?

A white glove migration is a complete platform migration service where a partner handles everything for you. They take full responsibility for moving your systems, data, and operations to a new platform. 

Your team provides access and makes decisions. The partner handles the execution.

This is different from assisted migration, in which you get guidance while doing most of the work. It also differs from tool-based migration, where software automates data transfer but you handle configuration, testing, and launch. In a white glove engagement, the partner is responsible for the outcome, not your internal team.

The term is used in many fields, including IT infrastructure, enterprise software, and ecommerce. You’ll also see it used for web hosting (for example, Wordpress site migration). This guide focuses on ecommerce platform migrations.

Here, white glove service means your partner takes care of almost the entire process. They handle your product catalog, customer data, and historical orders. They also set up your theme and storefront, handle URL redirects, and integrate with your enterprise resource planning (ERP) and email platform. They work with your reviews provider, subscription tools, and other systems in your stack. They run QA, validate performance, coordinate launch timing, and stay on call post-launch to catch issues early.

The “white glove” label signals a certain standard of service. Your partner should treat your migration journey like it’s their own launch.

What a white glove migration typically includes

Setting clear expectations up front will help prevent scope disputes and surprises down the line. Here’s what a complete white glove migration should cover—and what it usually won’t.

Usually included

Discovery and migration planning

The process starts with a full audit. It’ll map your current platform, catalog size, integration landscape, customizations, SEO footprint, and any constraints like peak-season blackout windows. This produces a documented migration plan with timeline, milestones, a risk register, and dependency mapping.

Data migration

Data migration covers products (including variants, metafields, images, and inventory levels), customers (profiles, addresses, marketing consent), and orders. Historical order depth varies by provider. Some migrate all historical orders; others focus on operationally relevant data (typically 12–24 months) to keep the project lean. Clarify this early.

Theme and storefront setup

Your new storefront gets built: theme installation, template configuration, navigation structure, homepage layout, collection pages, and core content types. This isn’t a website redesign. It’s a functional rebuild that mirrors your existing store’s structure and user experience.

URL mapping and SEO preservation 

Every indexed URL from your old site needs a redirect to the equivalent page on your new platform. This includes products, collections, blog posts, and any custom pages. Redirect validation ensures you’re not leaking SEO equity or sending customers to dead ends.

App and integration migration

Your operational systems need to reconnect, including ERP, product information management (PIM), third-party logistics (3PL), email and SMS marketing, subscriptions, reviews, loyalty programs, and analytics. The migration partner coordinates with vendors, configures connections, and tests how data flows between systems.

QA and performance validation

Systematic testing covers every critical area. There’s storefront user experience (UX), checkout flow, payment processing, shipping calculations, tax logic, discount and promotion behavior, transactional emails, inventory sync, and analytics event firing. Performance checks will validate page speed and Google Core Web Vitals against benchmarks.

Launch runbook and rollback plan

A documented launch sequence includes DNS timing, final data sync, redirect activation, monitoring checkpoints, and clear rollback triggers if something goes wrong. This needs to be scripted in advance, not improvised.

Post-launch hypercare

Most white glove engagements include at least 7–14 days of dedicated support after launch (although this can be longer for complex migrations or enterprise-scale stores). The partner monitors for issues, fixes bugs, validates analytics data, checks SEO performance, and handles the handoff to your ongoing support structure.

Performance and stability work

Migration is an opportunity to address performance issues that may have accumulated on your old platform. A thorough white glove migration includes performance benchmarking and optimization as part of the build phase. 

When Skullcandy replatformed to Shopify, they reduced homepage load time from 2.8 seconds to 0.8 seconds and cut product page load times in half. During a major product launch, the site handled a 200% spike in traffic with zero performance issues. That kind of stability comes from deliberate performance work during migration.

Often out of scope (or priced separately)

• Full redesign or rebrand: White glove migration rebuilds your store from a functional standpoint. If you want a new visual identity, UX overhaul, or brand refresh, that’s a separate design project.
• Complex ERP rewiring or custom middleware: Standard integration configuration is included. Building custom middleware, rewriting ERP logic, or making major system architecture changes usually requires separate scoping.
• International expansion strategy: Migrating existing stores is covered. But setting up new markets, tax entities, currency configurations, or localized storefronts for regions you don’t currently serve is a distinct project.
• Content rewriting or SEO content strategy: Your existing content gets migrated. Creating new content, optimizing copy for SEO, or developing a content strategy isn’t normally part of this process. 

The white glove migration process (step by step)

A structured ecommerce migration should follow a predictable sequence. While timelines and specific deliverables vary based on complexity, the fundamental phases stay the same.

1. Discovery

The migration partner collects all the info they need to plan accurately. The specific requirements vary by project, but a typical discovery phase covers:

• Current platform details and admin access
• Full integration inventory (what systems connect, how data flows, who owns each relationship)
• Catalog scope (SKU count, variant complexity, product data quality)
• Customer and order data volumes
• Subscription or loyalty program details (provider, token handling, contract constraints)
• SEO footprint (indexed pages, traffic patterns, high-value URLs)
• Peak season calendar and launch-timing constraints
• Success criteria (what “done” looks like for your team)

This list is representative, not exhaustive. Complex migrations often reveal new needs during discovery. These can include rebuilding custom features or managing third-party contracts that impact timing. 

A good partner will probe for these details, rather than assuming a standard checklist covers everything. This phase typically takes one to two weeks, depending on the complexity of your tech stack.

2. Data mapping and migration approach

With discovery complete, the partner maps source data to destination fields. 

Field mapping defines how information from your old platform translates to your new one. Product titles, descriptions, variant options, pricing, inventory levels, customer records, and order history all have source and destination fields. The mapping document shows how those fields link together.

This process often reveals inconsistencies that need addressing. Product data might have formatting variations accumulated over years of manual entry. Customer records might contain duplicates or missing fields required by the new platform. These issues surface during the mapping phase. That allows for cleanup before the transition rather than after.

Migration usually happens in waves:

• Test import: A subset of data validates the mapping logic and catches errors early.
• Full import: The complete dataset migrates to staging for validation.
• Delta import: A final sync captures any changes made between the full import and launch day.

This staged approach ensures you’re not discovering mapping errors on launch day. Each wave builds confidence that the final migration will be accurate.

3. Build and integration setup in a staging environment

With data mapping validated, the actual build work begins. The new store takes shape in a staging environment. This is a private version of your site. Here, the partner can configure, test, and refine the store without impacting your live operations or customers.

This phase brings together all the elements that make your store functional:

• Theme installed and configured
• Templates built for product pages, collections, cart, and checkout
• Navigation and menu structure created
• Payment gateways configured and tested
• Shipping rates and zones set up
• Tax settings configured (or tax provider integrated)
• Apps installed and connected (email, reviews, subscriptions, analytics)
• Integration endpoints configured and authenticated

Nothing goes live during this phase. The staging environment lets your team check progress and ask for changes. They can make sure the new store meets expectations before customers see it.

4. QA, performance, and security validation

Systematic testing covers every functional area of your new store. This is where assumptions are validated and edge cases get caught.

A good QA process checks each category methodically:

• Storefront UX: Homepage rendering, navigation, search functionality, collection filtering and sorting, product page display across devices and browsers
• Checkout: Add-to-cart behavior for all product types, cart calculations, guest and account checkout flows, payment processing, order confirmation
• Transactional emails: Order confirmations, shipping notifications, account creation, password resets, and any custom email triggers
• Discount logic: Coupon codes, automatic discounts, tiered pricing, buy-one-get-one (BOGO) offers, and any complex promotion rules
• Inventory: Stock-level accuracy, low-stock behavior, out-of-stock handling, inventory sync with external systems
• Analytics: Event firing, conversion tracking, attribution, revenue reporting, and integration with your analytics platforms
• Redirects: Sample testing validates mapping accuracy, with high-traffic URLs verified individually
• Page speed and core web vitals: Load times against targets, Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) within acceptable thresholds

SEO

Redirects are not optional. Every indexed URL from your old site needs a corresponding redirect to the new platform. Missing or broken redirects mean lost rankings, lost traffic, and frustrated customers hitting dead ends. Validate your redirect mapping thoroughly before launch.

Performance matters more than many teams realize during migration. When Skullcandy replatformed to Shopify, they reduced homepage load time from 2.8 seconds to 0.8 seconds and cut product page load times in half. That kind of improvement doesn’t happen by accident. It takes deliberate performance work during the build and QA phases.

5. Launch and rollback plans

Launch day—the cutover—is when months of preparation meet reality. For many teams, this is the moment of highest anxiety: the point where your new environment goes live and real customers start interacting with it.

Using a detailed launch runbook will transform it from a confusing practice into a stress-free, documented process. You’ll have clear checkpoints and contingency plans.

Pre-launch (24–48 hours before) 

The final countdown begins with a content freeze on your old platform. No new products, no price changes, no content updates. This ensures the delta import captures everything without chasing a moving target.

Your migration partner schedules the final data sync. They notify all stakeholders about the timeline. They also configure monitoring dashboards, so the team can watch for issues in real time after the switch.

Cutover window 

DNS changes initiate the switch, pointing your domain to the new platform. SSL certificates get validated to ensure secure connections. Redirects activate, sending traffic from old URLs to their new equivalents.

The final delta import runs, bringing across any orders or customer changes since the last sync. Test transactions confirm checkout is processing correctly. The team walks through the critical path (browse, add to cart, checkout, confirmation) to validate the full customer journey.

Rollback triggers 

Not every launch goes smoothly.

The runbook defines clear triggers for when to roll back. These might be checkout failure rates exceeding acceptable thresholds, payment processing errors, critical integration failures, or performance degradation beyond agreed limits.

If any rollback trigger hits, the plan includes steps to revert DNS and restore the previous platform. Meanwhile, the team works to fix the underlying issues. Having this documented in advance means decisions happen quickly, without panic.

Post-cutover (first 24 hours) 

With the site live, monitoring shifts to real-time error tracking. Customer service gets briefed on the escalation path for migration-related issues. The team spot-checks high-value URL redirects and verifies analytics events are firing correctly.

📋 Launch day checklist

Before cutover

• Content freeze confirmed on old platform 
• Final delta import scheduled and tested 
• All stakeholders notified with the timeline 
• Monitoring dashboards configured and accessible 
• Rollback plan reviewed with team 

During cutover

• DNS changes initiated 
• SSL certificates validated 
• Redirects activated and spot-checked 
• Final delta import executed 
• Test transactions processed through checkout 
• Critical user path validated end to end 

Immediately after

• Error monitoring is active 
• Customer service on escalation standby 
• High-value URL redirects verified 
• Analytics events firing correctly 
• Payment processing confirmed operational

5. Post-launch hypercare

The migration isn’t complete at launch. You enter hypercare: an elevated, short-term support phase right after a major cutover. In this window, a dedicated (and sometimes larger) support team is on standby to quickly identify and resolve any critical issues that emerge under real-world conditions.

The hypercare window usually lasts 7 to 14 days. Complex or enterprise transitions may take longer, though. This phase covers:

• Bug identification and fixes
• Analytics validation (conversion tracking, attribution, revenue reporting)
• SEO monitoring (indexing status, ranking changes, crawl errors)
• Integration troubleshooting
• Performance monitoring under real traffic
• Knowledge transfer to your team
• Documentation handoff

Analytics verification

Verify events post-launch. It’s common for analytics tracking to behave differently on a new platform, even when configured identically. You should validate conversion tracking, attribution, and revenue reporting against actual orders. This confirms data accuracy before you make decisions based on post-migration metrics.

At the end of hypercare, you’ll have a working store. You’ll also have validated integrations, clear analytics, and the documentation to manage operations properly.

White glove vs. self-serve migration: How to choose

Not every migration needs the white glove treatment. Here’s how to evaluate which approach fits your situation.

When white glove is worth it

High revenue at risk

If your store generates significant revenue, downtime costs compound quickly. According to ITIC’s 2024 research, the average cost of a single hour of downtime exceeds $300,000 for over 90% of midsize and large enterprises. A white glove partner’s launch discipline and rollback planning protect against catastrophic outages.

Complex integration landscape

There are more failure points for stores with deep ERP connections, multiple fulfillment partners, subscription programs, or custom middleware. Each integration needs testing, and problems in one system can cascade. White glove partners bring experience across these integration patterns.

Subscription or membership programs

When migrating subscribers, you need careful handling of payment tokens, billing schedules, and provider-specific constraints. Get this wrong and you’re manually rebuilding customer relationships. Confirm your migration partner’s experience with your specific subscription provider early.

Subscription tokens

Confirm your provider constraints early. Some subscription platforms have specific requirements for token migration, and not all migration paths are supported. Discovering these limitations mid-project can lead to delays and difficult conversations with existing subscribers.

SEO dependency

If organic search brings you a lot of traffic, redirect accuracy is non-negotiable. A white glove partner validates redirects systematically (rather than hoping the mapping spreadsheet is correct).

Tight timelines

Aggressive launch dates leave little room for learning curves. Partners who’ve done dozens of migrations know where problems hide and how to avoid them.

Limited internal technical capacity

If your team lacks migration experience or bandwidth, it makes sense to outsource execution to specialists.

Staples, the office supply retailer, replatformed to Shopify in under 12 months. They estimated it would have taken 24 months or longer on alternative enterprise platforms, and at more than twice the cost. That speed came from choosing a platform and migration approach designed for efficiency, not from cutting corners.

Bombas saw similar benefits when they migrated from Adobe Commerce to Shopify Plus. They saved $108,000 in platform costs in their first year and generated $17.2 million in sales. Their first Black Friday and Cyber Monday after migration had zero crashes. That’s proof that a well-executed white glove migration delivers stability when it matters most.

When self-serve can work

• Simple catalog: Low SKU counts with straightforward product data reduce migration complexity.
• Minimal integrations: If your stack is mostly native platform apps without deep external system dependencies, there’s less to reconnect and test.
• Low SEO risk: New stores or stores with limited organic traffic have less to lose from redirect imperfections.
• Strong internal technical expertise: Experienced developers who’ve done platform migrations before can often handle the work more efficiently than external partners, especially if they know your systems intimately.
• Flexible timeline: Without a hard launch deadline, your team can work through issues methodically without the pressure that causes mistakes.

White glove migration deliverables to ask for

When you’re evaluating migration partners, request specific deliverables. Vague proposals will cause scope disputes. Here’s what a thorough engagement should include:

Written migration plan with timeline

• A documented plan showing phases, milestones, dependencies, and responsible parties. 

Integration inventory and ownership matrix

• A complete list of systems being migrated and the configuration approach for each. Also, clarity on who owns each integration (partner, vendor, or your team). 

Data migration scope documentation

• Explicit definition of what data objects migrate, historical depth for orders and customers, and data cleanup responsibilities. 

Redirect plan with validation methodology

• The approach for URL mapping (including how redirects will be implemented) and the testing method to validate accuracy before launch. 

QA plan with pass/fail criteria

• What gets tested, who tests it, and what constitutes a passing result. This should cover functional and integration testing, and performance benchmarks. 

Performance targets

• Specific metrics the new site should meet: page load times, Core Web Vitals scores, checkout completion rates, and any other metrics you consider critical. 

Launch runbook with rollback plan

• The step-by-step launch sequence and documented triggers and procedures for rollback if critical issues emerge. 

Hypercare window and service-level agreements (SLAs)

• Duration of post-launch support, response time commitments, and scope of issues covered.

Red flags in migration proposals 

Watch for these warning signs when reviewing vendor proposals:

• No redirect plan: If SEO preservation isn’t explicitly addressed, expect problems.
• Vague data scope: “We’ll migrate your data” without specifics invites disputes.
• No rollback plan: Every launch needs an escape route.
• Missing performance targets: No benchmarks means no accountability.
• Unclear integration ownership: If it’s not clear who configures each system, things fall through the cracks.
• No hypercare window: Partners who disappear at launch leave you exposed during the riskiest period.
