[PVE-User] Migrating 4->5, from hammer to luminous: some shortcut?

[Marco Gaiarin]

I've stared today my cluster migration, currently migrating from ceph
hammer to jewel following:

	https://pve.proxmox.com/wiki/Ceph_Hammer_to_Jewel

I've found a temporary storage device (a NAS), and so i've migrated
(or stopped) roughly all VMs to that storage.


Next step would be migrating to luminous using official debian packages
from ceph:

	https://pve.proxmox.com/wiki/Ceph_Jewel_to_Luminous

Considering that i can move out (or stop) all Ceph traffic, it is
needed to upgrade ceph and then upgrade PVE?

Or i can have some shortcut, and upgrade directly to luminous using
official PVE 5 repository?


Why an intermediate passage via 'jessie ceph' packages is needed?


Thanks.
