Linux: Reverting from Version 8.1 to the previous V7 server
If you must revert to the previous version of the server after an upgrade, you must have a full database backup from your original version. You must also have the server installation media for your original version and key configuration files. Carefully follow the preparation steps before you upgrade the server. By doing so, it might be possible to revert to the previous version of the IBM Spectrum Protect™ server with minimal loss of data.
Before you begin
- Server database backup
- Volume history file
- Device configuration file
- Server options file
About this task
Use the same instructions whether you are reverting within releases or to an earlier release, for example, from 7.1.3 to 7.1.4 or from 7.1.4 to 6.3.6. The older version must match the version that you used before the upgrade to 8.1.

Procedure
Additional recovery steps if you created new storage pools or enabled data deduplication
If you created new storage pools, turned on data deduplication for any FILE-type storage pools, or did both while your server was running as a V8.1 server, you must complete more steps to return to the previous server version.
Before you begin
About this task
- You enabled the data deduplication function for any storage pools that existed before the upgrade to V8.1 program. Data deduplication applies only to storage pools that use a FILE device type.
- You created new primary storage pools after the upgrade and moved data that was stored in other storage pools into the new storage pools.
