Upgrade proxmox 5.3-5 to 6.0

[Fabio]

Good evening, since 2019 proxmox Virtual Environment 5.3-5 I have seen that you have published the new version 6.0. Can you tell me the correct procedure to upgrade my PROXMOX system?

Be care for huge corosync issue.

Clusters do require the pre-upgrade on all nodes to corosync 3.x , from what i have experienced on my 4-node cluster following the exact procedure as described in the update docs i had no issues at all.
