Goal: Install new/fresh OMV 5 while using existing data HD's. However, I want to configure settings during late evening hours, and reconnect original OS HD before bed.
EX. 10PM- disconnect old OS HD, connect new OMV5 HD, and tinker w/ settings 12 AM - Disconnect OMV5 HD, reconnect old HD. I imagine this would take me a week of configurations.
Will my data HD's be safe? or too risky? My old HD recognizes data HD's as unionfs
(old OS HD has OMV3, prefer new/fresh install for OMV5 on a new HD as well)
