Backing Up the File Pool

Control data backup files created prior to VM/ESA® version 1 release 2.1 may be used for restore only on releases prior to VM/ESA version 1 release 2.1. Therefore, you have to use FILESERV BACKUP as part of the procedure to migrate to z/VM® 7.3 from a VM/ESA version 1 release 2.0 or earlier system. This procedure is documented in VM/ESA 2.4: Conversion Guide and Notebook.

Storage group (user data) backup files created on your old release can be used on the new release. It is not necessary to immediately create new storage group backup files on the new release.
