Shopify migration and replatforming playbook: protect revenue while you move
A structured playbook for cutover weekends: parallel running, stock authority, redirects, integrations, and the comms plan that stops support from drowning.
Migrations are projects, but they are also incidents waiting to happen
The goal is not a perfect launch banner. The goal is no silent corruption of orders, stock, refunds, or customer access.
Phase 0 — inventory of reality
List:
- every integration line,
- every payment method in use,
- every URL that earns revenue,
- and every team workflow that touches orders weekly.
Phase 1 — parallel truth and authority
Decide the authoritative system for stock and orders for each day of the migration window.

Phase 2 — customer trust surfaces

Phase 3 — SEO and redirects

Phase 4 — integrations hardening
Rebuild only what you must — but rebuild with logs, retries, and idempotency:
Phase 5 — ownership after launch
Decide who maintains each line: agency vs in-house.
