Multiple software versions of cloud servers and databases

A cloud can support multiple versions of cloud server and database software.

The following rules apply:

  1. The major and minor version of the tenant database must be equal to or earlier than the major and minor version of the cloud server. For example a version 12 database can run on a version 12 cloud server or on a version 17 cloud server. A version 17 database can run on a version 17 cloud server, but a version 17 database cannot run on a version 12 cloud server.

  2. When a tenant database is involved in a mirroring or read-only scale-out system, then all of its database copies must run on cloud servers that are of the same major and minor version. In a mirroring system, the arbiter server must also be of the same major and minor version as the primary, mirror, and any scale-out database copies.

When you move a database from one cloud server to another, the target cloud server must be equal to or later than the major and minor version of the current database. A database copy can only be moved to a cloud server that has the same major and minor version as the cloud server of the tenant database. These rules also apply when load balancing databases.

When you restore a database, the database must be added to a cloud server that is either equal to or later than the major and minor version of the restored database. A database copy can only be restored to a cloud server that has the same major and minor version as the cloud server of the tenant database.
