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

TL;DR:

• A plan upgrade inside Shopify is a different project than replatforming from Magento, Adobe Commerce, or WooCommerce, and your source platform sets the budget and timeline.
• Inventory every URL, data object, app, integration, payment flow, tracking event, and operational dependency before build work starts.
• Run redirects, analytics, payment, tax, shipping, fraud, and dispute tests before cutover.
• Your chargeback ratio threshold keeps running through the cutover, so monitor it from week one alongside traffic, conversion, and payment failures.

A Shopify Plus migration

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.

Chargeflow integrates directly with your Shopify store to fight chargebacks and disputes for you, with no manual work required.

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 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.

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.

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.

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.
