@mira ... I would like to raise a question absolutely without a note of controversy, just to examine the reality of the facts.
I find it incorrect on the part of the Proxmox team to stop support for Proxmox VE 6.4 on July 31st when the 8 month version 7.x has problems, and I don't tell one individual, many individuals who pay for the Enterprise license.
I do not find it correct, it would be correct to extend support to release 6.4 at least until 7.x is really at the same level as 6.4, which (in my opinion) is NOT currently.
It is my thought, which does not want to accuse anyone, I know perfectly well that you are doing a GREAT job !!!
