I just wanted to let you know, that online migration of VM to different node, to differently named local storage seems to work perfectly for us. Good work PM team!

Does anyone have any problems with it?

This is a case where I migrated from hdd pool to ssd pool to different node.

Code:
root@p29:~# qm migrate 100 p30 --online --with-local-disks --targetstorage local-zfs-ssd
2019-02-27 16:21:45 starting migration of VM 100 to node 'p30' (10.31.1.30)
2019-02-27 16:21:45 found local disk 'local-zfs:vm-100-disk-0' (in current VM config)
2019-02-27 16:21:45 copying disk images
