Update 8.4 to 9.0 or 9.1?

[0x00000c]

Hello,

is it easily possible to upgrade our existing 8.4 installation to a specific 9.x version?
Our Backupvendor only fully supports 9.0, says "basic functionality" is offered with 9.1 and basically does not support 9.2 right now.
Since the development has been slow on the Backup side, my guess is, that PVE 9.3 will be out when they finally support PVE 9.2.
So, is there a way to update/upgrade to a specific PVE version to work around our Backup Support? Ideally without reinstalling the whole system.

I believe you will always get the latest point release when upgrading via APT interface. The only way for you to get a particular 9.x release is a fresh install from ISO. Then you will need to avoid full system upgrades and/or hold particular packages. The latter approach is error-prone and may lead to system instability.

You should be able to insert a install ISO of PVE 9.0 and update using the repositories located on the ISO.
