I run two checkmk sites, second is kind of a hot DR with notifications disabled. I take a backup of the prod site with omd backup and do an omd restore on the DR to keep it in sync. I recently updated both of them from 1.6.0p10 to 1.6.0p14 and then did a cleanup to get rid of p10. Now when I backup the prod site and try to restore to DR, it fails saying p10 has to be installed. But the prod site is p14 so why is it saying it needs p10? Do you really need to keep all your old versions after an update?
I would understand that my old backups might require this, but why a fresh backup taken after the update?
