Hi.
With the recent EOL of SLES12, and I assume tons of ZCM primaries still running on that OS, we really urgently need a more streamlined, "professional" way of being able to upgrade/migrate the underlying OS than this:
https://www.novell.com/documentation/zenworks-24.4/zen_sys_disaster_recovery/data/bj3xt3x.html
And that said, we need a better way to backup and restore Zenworks ZCM configuration, also for DR purposes. Ideally, there should be a single button or script that does a full, one-click restoreable backup of all ZCM configuration, that can be reapplied to a fresh installed server.
As for the current stance, that we should use the "Disaster Recovery" documentation to manually run through that tedious (and only party documented... "backup your database" is not a valid documentation in my book)) manual process to backup and restore a primary server:
I frankly don't see why *this* would work and be supported between two different Major SLES Versions, but an inplace Upgrade of the OS on a running ZCM would not be possible.
Especially considering, that with all the recent dockerization of ZCM services, it really shouldn't be impossible to come up with instructions or scripts how to make inplace upgrading a ZCM primary work.
I will start with just trying an inplace upgrade of a 24.4ZCM Primary Server running on SLES12 to SLES15, and see what real world issues I run into.
P.S: The linked docuemntation is yet again not up to it in itself, and is yet again just a huge C&P party, Not only does it suggest to consult the oracle documentation to backup Postgres, it also constantly contains informtation on Windows primary servers, which aren't even a thing any more.
