Inventory the dependencies
A VPS, dedicated server and public-cloud instance can have different resource, network and recovery models. Map your current machine, IP needs, storage and mitigation terms to the destination being evaluated without treating every OVHcloud product as interchangeable.
Separate failure domains
Review primary storage and backup placement, facility dependencies and the recovery procedure. A second copy only helps with the failures it is independent from. Test a restore before changing the live route.
Rebuild before switching
Take a consistent export, encrypt the backup and create the destination from a supported image. Restore application data, configure secrets privately and test the service under a temporary hostname. Verify jobs, mail, uploads and external integrations as well as the homepage.
Cut over with a way back
Lower DNS TTL in advance where useful, plan a final data synchronisation and switch only after validation. Keep the previous service available for an agreed rollback window, then remove billable resources and credentials after independent backups are confirmed. No fixed one-hour migration promise is made.
