I am new here so please forgive me if this information is somewhere else.
this post is similar .
I am still experimenting , but it seems I have better luck leaving container installs to
/DATA/AppData . the drive I am using is really not big enough. I have enough equipment to load two drives into drive caddies and boot off usb (clonezilla) and clone original onto newer larger dirve. Then I would need to get to the server stab and edit the blockid for the drive (lsblk ) .
Is that possible?
Not 
sure about any of that. What I am sure about is this tool comes native in Zimaos. I’ve used casa and found the drive management tools like I would find in a nas to be lacking. Zimaos takes everything that casa does and adds drive management/nas functionality with the ability to move container data to another location.
