A complex WordPress migration needs a plan for data, integrations and old URLs as well as the new hosting environment. Rehearse the cutover against realistic activity before moving the live site.
A complex migration is not a copy operation. It is a controlled transition across content, URLs, users, integrations, editorial workflows and infrastructure.
Define what must remain true
List the behaviours, data relationships, permissions, search visibility and operational processes that must survive the move.
Audit the source data
Measure content types, media, metadata, taxonomies, redirects and exceptions before choosing import tooling. Unexpected variation is normal in long-lived systems.
Design verification early
Use repeatable imports, reconciliation reports and representative acceptance cases. Verification should not depend on visually checking a handful of pages.
Plan cutover and rollback
Define freezes, deltas, DNS or routing changes, monitoring and rollback criteria. A migration is safer when every irreversible step has been postponed.

If this describes your current platform, start with the system, the constraints and the business goal. I can help you identify the highest-impact next step before more development is added.
Rehearse the cutover with realistic data
The migration plan needs to account for changes that continue on the live site. Orders, enquiries, comments and scheduled content can arrive after a staging copy is created. Identify which records need a final transfer and when writes will be paused or reconciled.
Test important old URLs against their intended destinations, including portfolio entries, media and category pages. A final HTTP 200 is not enough if the redirect ends on the wrong page. Check the destination, redirect count and canonical host together.
A complex WordPress migration also needs an explicit stop decision. Agree which failures prevent launch, who makes that call and how the original environment would be restored. After cutover, repeat the form, checkout, scheduling and indexing checks against the actual production domain.
