I use (indeed more than) two OMV servers, the newest, a fresh system one, has OMV 5.3.9 working, the older has OMV 4.x. [ I used the new system basically to fully install the OMV 5.3.9 system. ]
Now I want to upgrade the older OMV 4.x system (to OMV 5.3.9) by plugging in and boot the new 5.3.9-OS-disk on the old OMV box.
* Will this be possible?
* What are the important configuration files which need to be copied (and may be adapted) form the 4.x to the 5.x disk?
So to summarize: will upgrade from 4.x to 5.x be possible when using two system disks? Which files are needed to be copied then?
Your help is very appreciated.
I studied a lot of available information and found some information that it is currently impossible to programmatically upgrade a running 4.x system to 5.x, for example I found the information that a former script "omv-release-upgrade" has been removed, because it is not applicable to a 4 -> 5 upgrade.
