Migration process overview

Before starting the migration process, be aware of the restrictions that apply, and review the descriptions of system operations before and after the migration.

The following restrictions apply to the migration:

The V5 server running on z/OS® can be migrated only to an AIX® or Linux on System z® system.
Client data that is stored in server storage pools on tape can remain on the existing z/OS system, but database information must be migrated. Client data that is stored on random-access disks or existing FILE storage pools must be moved to tape before the migration begins.

Before the migration, the Tivoli® Storage Manager V5 server uses FICON® attached storage devices to access z/OS storage media.

The following figure illustrates operations before the migration.

The image is a graphical depiction of the V5 system before the migration.

After you migrate your system to a V7.1.1 server on AIX, the Tivoli Storage Manager V7.1.1 server uses Tivoli Storage Manager for z/OS Media to access z/OS storage media.

The following figure illustrates the system after migration to a V7.1.1 server on AIX.

The image is a graphical depiction of system operations after the migration to a V7.1.1 server running on an AIX operating system.

After you migrate your system to a V7.1.1 server on Linux on System z, the Tivoli Storage Manager V7.1.1 server uses Tivoli Storage Manager for z/OS Media to access z/OS storage media.

The following figure illustrates the system after the migration to a V7.1.1 server on Linux on System z.
