Timing depends on catalog and order volume, plugin-owned data, WordPress content, design scope, subscriptions, integrations, markets, data quality, and stakeholder approvals. A useful estimate follows discovery and includes at least one rehearsal, reconciliation, final data handling, cutover, and stabilization.
Find the plugin and content dependencies early
A usable timeline comes from the workstreams that need to meet at launch: catalog transformation, WordPress content, theme development, plugin replacements, connected systems, and operational sign-off. A large product file may be straightforward while one subscription or membership dependency determines the schedule.
Run a sample migration early enough to change the plan. Track unresolved mappings, app decisions, content approvals, and supplier access as explicit dependencies. Separate the time needed to build the store from the time needed to rehearse cutover, move final changes, and support the first live orders. Avoid choosing a date solely from a migration app’s estimated import duration.
What to check before deciding
- Estimate source cleanup and plugin replacement separately.
- Put sample import results ahead of the final deadline.
- Agree the handling of orders received during cutover.
- Reserve merchant testing and post-launch support capacity.
