How does the VPS upgrade work and how long does it take?

In the case of a VPS upgrade, the VPS may be migrated to another server base. At the end of the upgrade, the VPS will restart. VPS may not be available during migration. Migration time depends on disk size and type. You can follow the progress on the "Summary" tab in the VPS detail. The change retains the original VPS properties (data, assigned IP addresses, etc.).
