XCP-NG: not enough space on source host to migrate to new host

I am wanting to increase my XCP-NG drives but can’t migrate the running host to another host as I have not left enough disk space free.

I thought if I take the device offline first then it would not need much extra space to move it across but alas this does not seem to be the case.

I have back up so I can simply blow away and restore to new host but wonders if there was another approach I could take.

Managed to free up some space but CPU on two hosts are different and so migration not supported.. will do backups now that I have the space to work on and then restore them once I have upgraded the hard drives
