Upgrading to Proxmox 7

[sahostking]

We have cpanel centos 7 servers on proxmox 6 using LXC

Are there any known issues we should be aware of as we need to upgrade around 80 LXC containers as systemd is outdated on these and they using centos 7.

Anyone have experience or aware of any known issues we should be aware of.
Planning to start this weekend after some proper testing.

hi,

yes, take a look here [0].
basically if you're going to be running so many centos 7 containers with old systemd version, you could use the older cgroup version by setting it on your PVE node's kernel parameter (see link). alternatively you could try installing a newer systemd version on the containers.

for the general upgrade procedure from 6 to 7, take a look here [1]
