Migration to PMG6

[chebedewel]

We are running 5 PMG5.2 (+ one dedicated for quarantine), the idea is to do a fresh install of PMG6, have it join the cluster, and after a week or so, move the licence from a 5.2 to this new one, and shutdown the first old one.
Can this be done ? Can this new PMG6 become the master (will the others PMG5.2 keep on working ?)
What would be the best way to upgrade the quarantine server, fresh install or upgrade ?
Thanks for your help and hints !

the upgrade is described on the wiki: https://pmg.proxmox.com/wiki/index.php/Upgrade_from_5.x_to_6.0

I hope this explains everything - if not please ask!

You didn't really answer any of my questions, so I followed the wiki.
I've tried twice the new installation method, with the same result for the licence (from the report):

# pmgsubscription get

serverid: ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456

What can I do to fix this ? is it possible ? maybe some information is missing from the wiki ?

Thanks for any help in this matter
