Hi Shain,
We have done a few upgrades of 3-5 node clusters;

We are thinking about upgrading our existing Proxmox 3.4 cluster and I
was hoping to get some insight on a few of our currently open questions:
1)Should we stop at Proxmox 4.4 or does Proxmox 5.0 seem stable enough
for production environments at this time?
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.
2)Is it possible to have 2 separate Proxmox clusters on the same
subnet? We are trying to decide on an in place upgrade vs setting up a
new cluster and moving things over in a more controlled manor.
If we decided to invest in some new hardware for a new cluster we
would have to run 2 clusters on the same subnet for several weeks
while the migration took place...is this an issue?
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.
3)We are wondering about real world upgrade experiences in terms of
people who decided to do the in place upgrade...how many issues...if
any were raised using the apt-get upgrade method?
If you had to do it again would you still do it the same way?
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.
Cheers
