I would like to install 6.0 on a new larger server, then connect it to an existing cluster and move the existing containers/vm's to it and when complete remove the old servers from the cluster. Anyone had issues moving containers/vm's to the new version of Proxmox?
 
U want to live migrate the running vms to the new larger node?
I did an upgrade from 5.4 to 6 without any issues. I moved the disks from ceph storage to local. After upgrade to 6 and to ceph nautilus, i moved it back to ceph.
But i have not tested a cluster 5.4 with one node with pve6. It should work to move/migrate the vms/containers to the new large pve6 node.
How is your configuration for the disks of your vms/containers?
 
Just move them. They can be turned off. I am in the process of doing this now. All storage is ZFS at this point.
 
I have basically the same problem but without the complication of a cluster, i.e., just a single proxmox 5.4 node which I would like to move to new hardware and proxmox 6.0. Downtime is acceptable. The hardware is nearly the same, just a slightly faster CPU (same generation) and SSD storage instead of HDD.

What would be the best strategy? Would this work?
  1. Backup all VM/CT to a NAS
  2. Backup the config to the NAS (what exactly do I need here?)
  3. install pve 6.0 on new hardware
  4. add old config
  5. restore VM/CT from NAS?
The new server has identical

yes that should work

Backup the config to the NAS (what exactly do I need here?)
if you're installing from scratch, just your guest configs in /etc/pve/lxc/ and /etc/pve/qemu-server and /etc/pve/storage.cfg should be enough
