How to Migrate to Shopify Plus: The Complete Pre-Migration Checklist

To migrate to Shopify Plus, you move your store's data, theme, apps, and payment setup onto Shopify's enterprise plan while preserving your SEO, order history, and revenue. It usually takes 6 to 12 weeks, based on practitioner benchmarks, and Magento or Adobe Commerce stores often run 12 to 24 weeks.

What Is a Shopify Plus Migration?

A Shopify Plus migration moves your products, customers, historical order data, theme, apps, and payment configuration onto Shopify's enterprise plan. The goal is a clean cutover that keeps your rankings and revenue intact.

Shopify Plus is Shopify's plan for high-volume and enterprise merchants. It adds tools like Shopify Functions, more staff accounts, and higher API limits.

Most merchants migrate from one of three places. You may be leaving Magento or Adobe Commerce, coming off WooCommerce, or upgrading from standard Shopify to Plus. Each starting point changes how much work the move takes.

A Shopify Plus replatform means moving from a different platform onto Shopify Plus, which is a full rebuild. Going from standard Shopify to Plus is a plan change on the same platform, so most of your store carries over. Which path you are on sets your budget and timeline.

If you run separate regional stores today, decide before you migrate whether they become markets inside one store or stay as separate stores. Our guide to Shopify Plus global expansion covers that structure and the cross-border dispute risk that comes with it.

One part of the move is easy to underestimate: your payment gateway and checkout. Plus lets you customize checkout far more deeply (see our guide to Shopify Plus checkout customization), and rebuilding it is also where fraud and chargeback protection quietly break. It is the line item most migration plans scope out entirely, and we cover the fix later in this guide.

For the full picture of what the plan offers, see our Shopify Plus guide. For the mechanical import steps, Shopify's official migration guide is the authority. It outlines how to migrate your store to Shopify from another platform.

Here is what a Shopify Plus migration includes:

• Data migration: Move your products, collections, customers, and historical order data so nothing is lost.
• Theme rebuild: Recreate your storefront design on a Shopify theme, since designs rarely transfer one-to-one.
• App re-integration: Replace old plugins with Shopify apps for reviews, email, search, and support.
• Redirects and SEO preservation: Map old URLs to new ones with 301 redirects so you keep your rankings.
• Payment and checkout setup: Reconfigure your payment gateway, taxes, and checkout, including fraud and chargeback protection.

Shopify Plus Migration Timeline

The 6 to 12 week range is a practitioner benchmark from agencies that run migrations, not an official number from Shopify, so treat it as a planning estimate. Three things drive it: how much data you move, how custom your design is, and how many apps you rebuild. A small store with a clean catalog lands near the low end. A large store with heavy customization lands near the high end.

Here are the typical phases and how long each one tends to take:

A fraud and chargeback audit fits inside the staging and QA phase at near-zero extra cost. You are already testing checkout, so testing your protection at the same time is nearly free. Most teams run these phases with an implementation partner, and our list of top Shopify Plus agencies is a starting point for vetting one. For build-focused partners, see our comparison of Shopify Plus development and design agencies.

Your starting platform is the biggest driver of timeline. This comparison shows rough ranges by source platform:

Upgrading from standard Shopify to Plus is the fastest path. It is a plan change on the same store, so your products, customers, orders, and apps stay in place, and the remaining work is checkout, app, and fraud-rule testing.

Magento takes the longest because its data and extensions are the hardest to move. According to a mid-market Magento migration benchmark, a Magento to Shopify Plus migration takes 12 weeks for a mid-market merchant. That merchant runs 5,000-25,000 SKUs, a single storefront, two to three locales, and a standard Magento 2 extension stack. The same source splits the 12 weeks into roughly four weeks of discovery and architecture, six of implementation and integration, and two of pre-launch validation and cutover, and puts larger operations at 16 to 20 weeks.

If you are migrating off Magento specifically, its chargeback dynamics differ from Shopify's. See our breakdown of chargeback software for Magento merchants for what changes once you cut over.

Pre-Migration Checklist

Most cutover problems start with skipped prep work. Run these six steps before you build, and treat each one as a gate you clear before moving on.

Work the list in order. Data and apps come first, because your theme, redirects, and payments all depend on them.

Two details from Shopify's migration guide catch teams off guard. Apps cannot be transferred, so you reinstall each one from the Shopify App Store. And when you import historical orders, any staff member set to receive new order notifications gets a new order email for each imported order, so switch those notifications off before the import.

For the official milestones, the Shopify Plus launch checklist offers guidance and resources for important milestones when launching on Shopify Plus. Its 14 sections run from migrating your data to post-launch tasks, including international sales tools, subscriptions, and Shopify B2B, but it has no line item for fraud rules, chargeback alerts, or dispute workflows. That gap is why migrations create risk: the platform's own guidance will not catch it, so your team has to build this check in deliberately. If wholesale is part of the move, our Shopify Plus for B2B guide covers which B2B features need Plus. Pair the checklist with our roundup of the common Shopify chargeback mistakes so you do not carry old gaps into your new store.

Common Migration Mistakes

Most migration problems tend to come from rushing, skipping tests, or assuming everything transfers on its own. Each of these mistakes is simple to prevent.

• Skipping redirects: Launching without 301 redirects sends old URLs to dead pages. You lose rankings and traffic on day one.
• Not migrating historical order data: Leaving old orders behind breaks reporting, support, and returns. Your team loses the history it needs.
• Forgetting app re-integration: Some tools have no Shopify twin. Each one needs a new app and fresh setup, so test them all.
• Testing on production instead of staging: Editing the live store exposes shoppers to broken pages. Do the work in a staging environment first.
• Rushing go-live: Launching before QA is finished turns customers into your testers. Budget real time for testing.
• Ignoring fraud protection until go-live: Reconfiguring checkout without checking fraud rules opens a gap you will pay for later.

What to Check Before You Flip the Switch

Rebuilding checkout is when chargeback and fraud protection gaps get introduced, because the fraud rules and dispute workflow from your old store do not always come with it. A mid-migration audit is the cheapest time to close them.

Friendly fraud is a chargeback where a real customer disputes a charge they actually made. It is easy to miss during a migration, since your old defenses may not follow you. Rebuilding that protection after launch costs far more than checking it now.

The stakes are rising. Mastercard's June 2026 update, based on Datos Insights research, projects that global chargeback cost will rise from $36.9 billion in 2026 to $46.1 billion in 2029.

Fraud is expensive too. The 2026 LexisNexis True Cost of Fraud Study found that US retail and ecommerce merchants now pay $5.13 in total costs for every $1 of direct fraud loss.

Where Chargeback and Fraud Risk Enters Your Migration

Run this audit before you go live:

This is the step that protects your revenue at launch. Chargeflow automates this layer end to end, using Alerts for pre-chargeback deflection and Automation for evidence collection, submission, and recovery. Our Shopify Plus chargeback protection guide goes deeper, and you can see how automated protection works on Chargeflow for Shopify.

Post-Migration: What to Monitor First

Watch your store closely for the first 30 to 90 days after launch, because that is when migration issues surface. Small problems caught early stay small.

Set a baseline before you launch so you have something to compare against. Save your current traffic, rankings, conversion rate, and chargeback ratio. Then check the same numbers each week after go-live.

Your chargeback ratio threshold does not pause for your migration. In AP, Canada, EU and the U.S., the standard Visa VAMP Excessive Merchant test requires both a ratio of at least 1.5% and at least 1,500 fraud reports plus disputes in a month, when the acquirer is not Above Standard or Excessive. The VAMP ratio is the combined count of TC40 fraud reports and TC15 disputes divided by the count of settled card-not-present VisaNet transactions (TC05). Mastercard ECM also uses its own count-and-ratio test regardless of migration timing. Regional and acquirer criteria differ. For Visa, certain pre-dispute resolutions and qualifying CE3.0 fraud reports are excluded, depending on extract timing; one transaction can generate both a fraud report and a dispute. Winning a case generally does not remove its report. Confirm the applicable criteria, exclusions and consequences with your acquirer. See Visa’s VAMP fact sheet for regional criteria and reporting exclusions.

Assign an owner for each metric so nothing slips. One person watches SEO, another watches checkout and payments. Clear ownership turns monitoring into fast fixes.

Downtime is costly, which is why fast monitoring matters. Per ITIC's 2024 downtime survey, the average cost of a single hour of downtime now exceeds $300,000 for over 90% of mid-size and large enterprises. That figure spans many industries, not just ecommerce, but the lesson holds.

Monitor these signals first:

• Monitor 404s and redirect errors: Scan for broken links and missing redirects, which bleed SEO and frustrate shoppers.
• Monitor organic traffic and rankings: Compare against your pre-launch baseline to catch drops early.
• Monitor checkout conversion: Watch for a dip that signals a broken step in the new checkout.
• Monitor payment success rate: Confirm transactions clear as expected across every payment method.
• Monitor early chargeback signals: Track your chargeback ratio and dispute volume from week one, before a spike hardens.

Perguntas frequentes

How long does a Shopify Plus migration take?

Most Shopify Plus migrations take 6 to 12 weeks, based on practitioner benchmarks, with the exact timeline driven by your source platform and catalog size. A Magento or Adobe Commerce migration often runs 12 to 24 weeks because its data is harder to move.

How much does it cost to migrate to Shopify Plus?

The cost of a Shopify Plus migration varies widely with store complexity, data volume, and how much custom design and app work you need. The platform itself starts at $2,300 USD per month on a 3-year term or $2,500 USD on a 1-year term, per Shopify's Plus pricing page, before agency, app, and testing costs. Our Shopify Plus pricing guide breaks down the rest of the bill.

Will I lose my SEO rankings when I migrate to Shopify Plus?

A migration can cause temporary organic volatility, but a complete URL map, one-to-one 301 redirects where appropriate, preserved metadata, validated canonicals, and post-launch monitoring reduce avoidable loss. Skipping redirects is the main reason merchants see traffic drop after a migration.

Can I migrate my historical order data to Shopify Plus?

Yes, you can migrate your historical order data to Shopify Plus, and you should, because your team needs that history for reporting, support, and returns. Verify that record counts match after the import to confirm nothing was lost.

Does migrating to Shopify Plus increase my chargeback or fraud risk?

Migrating to Shopify Plus can increase your chargeback or fraud risk if you rebuild checkout without carrying over your fraud rules, alerts, and dispute workflow. Auditing your protection during the staging phase closes that gap before go-live.
