We haven't used Proxmox 5.0 yet because we're using Ceph in almost all 
clusters. I think we'll start migratin when PVE 5.1 is out, now that 
Ceph Luminous is final.

Yes, it is possible (use different cluster name when creating the 
cluster). Also, Proxmox v3 and v4 cluster system is different, which is 
why you have to re-create the cluster when upgrading.

Yes, we always have done in-place upgrades. If you find any issue it 
isn't Proxmox related, but other packages you may have installed. Fix 
them as you would in a non-proxmox Debian upgrade and you're good.
