A few year ago, we ordered 8 servers for a new vmware cluster.
One of the servers exposted unstability: Memtest failed after a few hours.
It took me weeks with dell support to rule out memory stick and mainboard defect to finaly discover one...
I would upgrade one node after the other:
* evict vm/lxc to other nodes before upgrading
* conduct the upgrade like you said (pv8to8 checks...) (and doing it on an empty node)
* migrate back a few "ginea pigs" vm ( to verify network...)
* once...
you might try to migrate vm one by one to a node in the new cluster ( qm remote-migrate command ). shared storage ( nfs) can help for this task
* move volume to nfs storage
* qm remote migrate
* re migrate to local storage
I tried PBS 4 Beta with a QNAP NAS QObject Storage and it works but don't think you will get better performance, after all it's just an additional abstraction layer on top of the already existing storage layer of the NAS.
The good thing about...

Datastore is hosted on the NAS and connected to the VM via NFS.
I've yet to upgrade to PBS 4.0 but I'm wondering:
Instead of NFS bewteen VM...
