Yes, it is. I've only done this on amd64's with SATA drives, but I can't imagine the procedure and end result is much different.
1. SSH your server and become root.
2. Stop docker
(Quelltext, 1 Zeile)
3. cd /var/lib
4. We'll copy the docker folder just in case something goes wrong... (I would not recommend making this a subdirectory of other directories, sharing over SMB, etc.. as docker puts some pretty harsh permissions on this folder... so I'd just put it right under the UUID by itself…
