Know what you are moving before you move it
An application may depend on a database, uploads, background jobs, email, domains and external credentials. An inventory prevents overlooking a component that is rarely visible but essential. Review data volume, load, backups and the destination environment. If the project must move independently of neighbouring services, examine shared folders, databases and configuration. Finding a hidden dependency at this stage is better than discovering it during the domain switchover.
Prepare the destination separately from production
Deploy the agreed version, restore a data copy and verify key journeys in a separate environment. Then plan the final data sync and switchover. Some systems need a short write pause; others allow different arrangements, so zero downtime cannot be promised universally. Know when rollback remains possible and how to handle data created after the switch. Preserve the previous environment until the agreed verification period is complete.
After launch, check more than the homepage
A working homepage does not prove notifications, uploads, scheduled jobs or integrations are functioning. Run the agreed journeys and watch for errors after the switch. Update access, backups and instructions for the destination. Ongoing support can cover fixes, updates and improvements, with scope and response arrangements agreed separately. Migration cost depends on the project and its data, not merely the number of servers or the size of an archive.
Two useful questions
Can a single site be moved out of a shared system?
Often, yes, after reviewing dependencies. Shared data, configuration or background tasks may need to be separated carefully before an independent move.
Is the old server deleted immediately?
No, not by default. Retention, backups and removal are agreed after verifying the new environment and the rollback plan.
