Can we do FSbased sed restore postgre 14 to 15

​@BillyBoo can you share the source of the two statements? I think you took this one "higher to lower” from an older version being FR20 as newer releases mention that it should be possible to restore to a newer version. As FR20 documentation was created at a time in where the PostgreSQL was also a much older version it could very well mean that this was a PostgreSQL limitations that was addressed in a newer version. So, just make sure you are on documentation of the version that you are running and I would advice you to test it out. I assume the action that you are taking is a planned action and not a DR recovery.

Before You Begin

Check whether you meet the following requirements:

• The source and destination clients have the same major version of PostgreSQL Server.

Are you using block-level backups as this documentation page is based on a specific setup that uses that instead of the default protection method. 

Hi

it says the same thing even if there is no block-level backup

Before You Begin

• Verify that you have a PostgreSQL instance on the CommCell Console both at the source server and the destination server.

• The versions of PostgreSQL on both the source server and the destination server must be the same.

Again this is a specific e.g. advanced restore option. However, the documentation page for a regular recovery states the same as where the essential documentation differs. I think the expert documentation is incorrect.

Essential: Verify that the PostgreSQL software version on the destination is the same version or higher than the version of source.

Expert: Verify that you are restoring the File System backups of the same version of PostgreSQL and not from higher to lower or lower to higher.
