Shopify Migration and Replatforming
The risky part of moving to Shopify is the data nobody mapped: customer records, order history and subscription contracts. These guides are for brands leaving Salesforce Commerce Cloud or another legacy system, and for the teams who own data, finance and support during the move. Posts cover replatforming checklists, checkout limitations, and customer and order history migration. A large group covers subscriptions, including contract export, billing cycles, failed-payment recovery and QA before the first renewal. Loyalty, gift subscription, LTV tracking and POS migration each get their own guide.
