Proxmox 5 and switch from Ceph RBD to NFS (and after upgrade PVE)

[alessice]

Hi,

I'm running a cluster with 8 nodes of PVE 5.4 with Ceph RBD (HCI) as storage. For many reasons I prefer to switch to NFS (NetApp All Flash) for shared storage, and after upgrading PVE to the latest release.

My idea is to:

- configure NetApp and add the NFS storage to all PVE nodes
- migrate all VM from Ceph to NFS
- disable and remove Ceph RBD as storage
- migrate/move all vm away from the upgrading node
- upgrade the PVE node to the next version (5->6)
- do it for all PVE nodes
- upgrade the PVE node to the next version (6->7)
- do it for all PVE nodes

Do you think this is the right procedure?
Thanks
