Short answer: Minimise downtime by copying and testing the site before changing DNS, lowering DNS TTL in advance, freezing risky changes during the final sync and keeping the old host available until the new site is verified.

Quick decision checklist
- Complete file and database backup
- Staging or hosts-file test
- Documented DNS and email records
- Final database sync
- Rollback window
Reasons to pause
- Cancelling the old host before verification
- Changing domain nameservers without copying email records
- Testing only the homepage
Prepare before the move
Inventory domains, DNS, mailboxes, cron jobs, SSL, redirects and integrations. Create a full backup and verify that it can be opened. Reduce TTL ahead of the planned switch where appropriate.
Test the new copy privately
Check login, forms, search, media, redirects, analytics, scheduled jobs and transactional email. For stores, use a maintenance or order-freeze plan during the final database move.
Switch and observe
Change only the required DNS records, monitor both environments and keep the old service active. Verify from multiple networks and inspect error logs before declaring success.
