Migration Overview

If you already sell custom products with another app, you do not need to rebuild your whole Shopify store. You do need a clear plan for what Custy can take over and what you set up again.

This overview is the map. The guides under Migration walk you through each part, one step at a time.

What you keep

Your Shopify store stays the same. Products, collections, theme, checkout, and orders stay in Shopify.

  1. 1Your Shopify products and variants stay in place
  2. 2Your theme and checkout stay yours
  3. 3Past Shopify orders stay in Shopify
  4. 4Your brand, domain, and payment settings stay unchanged

What you rebuild in Custy

Custy does not import another customizer’s designs, print areas, or pricing rules automatically. You recreate those settings in Custy so shoppers get a clean, supported setup.

  1. 1Turn products into custom products in Custy
  2. 2Rebuild sizes, colors, and print areas
  3. 3Rebuild printing types and pricing rules
  4. 4Turn on Custy in your theme so Customize It shows
  5. 5Test a few products before you remove the old app

Best order to migrate

Follow these guides in order:

  • Read From Inkybay & Competitors if you are leaving another customizer
  • Follow Existing-Store Workflow for a live store
  • Use Side-by-Side Testing before shoppers rely on Custy
  • Complete the Pre-Switch Checklist
  • Keep Recovery & Rollback handy if something looks wrong

Before you start

Finish Getting Started first if Custy is not installed yet. Then set up at least one custom product under Products so you know the screens before you migrate a busy catalog.
