Is there a way to upgrade from 2.2.14 to 4.x without loosing seetings and data ?
I'm running omv 2.x with a large software raid 6 managed by omv (with the ext4 data-partition), a lot of shared folders, a few users and the following plugins: plex, SABnzbd, Jdownloader and cups.
The system itself runs on a small raid1 partition (hardware-raid).
I read that I have to do a complete new install of the systemdisk with omv 4.
How can I keep my settings (esp. the raid config and shared folders / users) ?
I think the 4 plungins shoud be no problem, cups is available for 4.x and plex, SABnzbd and jdownloader can be installed with docker.
