I have used OMV for a long time and left it on 2.2.14 Stone burner because it simply works.
I've convinced myself it's time to update/upgrade to a newer/latest version.
The main reason is SMB and Windows 10 2004 issues I've been having recently.
After reading on this forum I understand that I cannot update/upgrade directly to the latest version as it's approximately 3 releases old.
What I would like is some guidance to check:-
What setup I have
What, if any, config backups might be useful/necessary even if only for reference
Then if possible and not asking too much I'd like some instructions on the process to install the latest version without losing access to my data.
