I have OMV4 which has been upgraded from OMV2 or 3 as i remember.
It has a number of apps from outside OMV e.g. tomcat and openkm, etc.
I want to get a clean install of OMV and move my data and system config / settings e.g. firewall rules, etc across.
In particular, i use a DOM for the system drive, so i can put in a fresh one and create a new system, but how to migrate the settings from OMV across without the data drives, etc being reformatted
