Inventory the current environment
Record the platform, storefront, extensions, custom functionality and connected systems. Include the people who know how the business actually uses them.
List product, customer, order and content data separately. For each dataset, identify the source owner, export method, quality concerns and destination requirements. Decide which historical information must remain accessible even if it does not move into the live platform.
Define the intended destination
Write down the customer journeys and operating workflows the destination must support. Identify functionality that will be recreated, replaced or retired.
Check assumptions about account access, product relationships, order status and third-party connections. Those details can affect the customer and operations experience after launch.
For an unresolved platform choice, use the platform-selection framework.
Build the URL transition plan
Create a mapping from existing important URLs to their appropriate destinations. Review redirects, internal links, canonical URLs and sitemap changes. Preserve relevance when choosing redirect targets.
Google’s guidance explains that site moves are processed per URL and can take time. It recommends preparing URL mappings and monitoring the move. Search visibility should therefore be monitored after launch rather than treated as a guaranteed constant. Google Search Central’s site-move guidance provides the technical reference.
Rehearse data transfer and reconciliation
Test the mapping and transformation rules using representative records. Include incomplete, unusual and duplicate data where those conditions exist in the source.
Reconciliation should check more than record counts. Verify relationships and commercially important values, such as product identifiers and the information required for fulfillment. Record discrepancies and who decides how to resolve them.
Test the connected business process
Follow key journeys from storefront action to operational result. Confirm what happens in downstream systems and what an operator sees when part of the sequence fails.
Use the integration planning guide to define ownership and exception behavior for each connection.
Write the cutover and recovery decisions
Document the final data synchronization approach, any trading restrictions, the launch checks and the people authorized to proceed or stop.
Recovery planning must account for writes made after the transition begins. Once new orders exist, returning to an earlier system can create data conflicts. Define the recovery options and their limits before the cutover.
Assign the post-launch checks
Name owners for order reconciliation, customer-reported issues, integration failures, crawl or redirect problems and other agreed signals. Define how issues are prioritized and communicated.
The immediate launch check confirms an initial state. Continued monitoring shows how the new system behaves under real use.
What a readiness review should produce
Leave the review with an issue list, a named owner for each unresolved item and clear release criteria. Missing evidence should become work to complete, not an assumption hidden inside the schedule.
