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

A Shopify Plus migration is the process of moving an ecommerce store onto Shopify's enterprise plan, along with its data, theme, apps, and payment setup. It usually means moving from Magento, WooCommerce, or standard Shopify while preserving your SEO, order history, and revenue.

What Is a Shopify Plus Migration?

A Shopify Plus migration means rebuilding your store on Shopify's enterprise plan and moving everything that matters with it. That includes your products, customers, historical order data, theme, apps, and payment configuration. 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. A migration is how you move your existing store onto that plan.

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.

There is a difference between a replatform and a plan upgrade. A 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.

Shopify Plus replatforming is the term for that full rebuild on a new platform. It is the harder path, but it unlocks the enterprise features most growing brands want. Knowing which path you are on sets your budget and timeline.

One part of the move is easy to underestimate: your payment gateway and checkout. Rebuilding checkout is also where fraud and chargeback protection quietly break, and it is the line item most migration plans scope out entirely. 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

A Shopify Plus migration usually runs 6 to 12 weeks, though your source platform can push that higher. These figures are practitioner benchmarks from agencies that run migrations, not official numbers from Shopify. Treat them as planning estimates.

Three things drive the range: 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:

1. Discovery and audit (1-2 weeks): Map your data, apps, integrations, and URLs so you know the full scope before you build.
2. Data migration (1-3 weeks): Export and import products, customers, and historical order data, then verify the counts match.
3. Theme rebuild (2-4 weeks): Recreate your storefront design and templates on Shopify.
4. App re-integration (1-3 weeks): Set up and test the Shopify apps that replace your old plugins.
5. Redirect mapping and SEO (1-2 weeks): Build your 301 redirect map and confirm metadata carries over.
6. Staging and QA (1-2 weeks): Test everything in a staging environment, a private copy of your store shoppers cannot see.
7. Go-live and monitoring (ongoing): Flip the switch, point your domain, and watch the store closely.

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.

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. Switching the plan itself happens at the account level, while a full data migration and build-out still varies with store complexity.

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, and a standard Magento 2 extension stack.

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

The work you do before you build decides how smooth your Shopify Plus migration goes. Skipping this stage is where most cutover problems start. Run it first, and treat each step as a gate you clear before moving on.

1. Audit your data: Inventory every product, customer, and order you need to move, and clean up duplicates before they follow you over.
2. Inventory your apps and integrations: List every plugin your store relies on, then find the Shopify app that replaces each one.
3. Plan your theme and design: Decide what to rebuild as-is and what to improve, since designs rarely transfer one-to-one.
4. Map your redirects: Plan a 301 redirect for every old URL so links and rankings land on the right new pages.
5. Set up your payment gateway: Configure Shopify Payments or your gateway with taxes and currencies, then test real transactions in staging.
6. Review your chargeback, fraud, and return policy setup: Confirm your fraud rules, alerts, and dispute workflow move over too. Most plans skip this step.

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

For the official milestones, the Shopify Plus launch checklist offers guidance and resources for important milestones when launching on Shopify Plus. It is worth noting what that checklist does not cover: it walks through payments, checkout customization, and test-order scenarios, but it has no line item for fraud rules, chargeback alerts, or dispute workflows. That gap is exactly why migrations create risk, the platform's own guidance will not catch it, so your team has to build this check in deliberately. 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 are avoidable. They tend to come from rushing, skipping tests, or assuming everything transfers on its own. These are the mistakes that cost merchants the most, and each one 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

Migrating payment processing and checkout is exactly when chargeback and fraud protection gaps get introduced. When you rebuild checkout, 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 those gaps.

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 forecasts that the global cost of chargebacks to merchants will reach $42 billion by 2028, with nearly half reported as fraudulent.

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, and $5.23 in Canada, the first time both markets have crossed the $5 mark.

Where Chargeback and Fraud Risk Enters Your Migration

Run this audit before you go live:

• Check your payment gateway config: Confirm Shopify Payments or your gateway is live, with taxes, currencies, and payout details correct.
• Check your fraud rules: Rebuild the fraud filters and risk thresholds you relied on before, since they do not carry over. Turn on 3D Secure for higher-risk orders while you rebuild them; it shifts liability to the card issuer during exactly the window when your own rules are still incomplete.
• Check your chargeback alerts: Make sure real-time chargeback alerts are active so you can stop disputes before they post.
• Check your dispute-evidence automation: Confirm your evidence and submission workflow is connected, so no deadline gets missed.
• Check your refund and return policy: Align your policy and checkout copy so friendly fraud has fewer openings.

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.

Post-Migration: What to Monitor First

Launch is the start, not the finish. Watch your store closely for the first 30 to 90 days, 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. Visa's VAMP program still measures you against its 1.5% excessive-merchant tier, and Mastercard's ECM program still counts your ratio, whether you migrated three weeks ago or three years ago. A dispute spike during cutover puts you on the clock for the same monitoring programs and fines as any other month.

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.

Preguntas frecuentes

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. Plan your budget around your specific scope, since larger catalogs and heavy customization raise the total.

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.

Protect Your Revenue Before You Cut Over

Migrating to Shopify Plus without auditing your chargeback and fraud setup trades one risk for another: a clean new platform with a broken dispute defense. Talk to Chargeflow before go-live and close that gap on the same timeline as the rest of your migration.
