Hope this one won't have a lot of pointing fingers at me (total noob). I'm about to abandon my good old 716+II (because if an old kernel which prevents me from running a few dockers). Long story short: I have HP Elitedesk G4 800 here collecting dust. And a spare 500gb M2. So the idea is to install Proxmox, and the Xpenology on the M2. Question: any easy way to use the 2 HDDs from the 716? With all config/container etc.? Any headsup would be greatly appreciated.
