Hi,

this is a bit of an insane question, but anyhow. I've got a client with a legacy proxmox host with some legacy containers
Proxmox itself was updated over time. The legacy service VM were left behind, some are running CentOS v6.3

I was able to do some trickery to get the CentOS VM 6.3 updated to 6.10
which was some drama due to SSL/TLS version issues (can't update yum without .. version of yum .. that will talk to the repo .. SSL not support errors etc - thankfully mitmproxy was able to help out // get around that.)

Now, I was trying to follow some hints as per > https://wiki.almalinux.org/elevate/...7.html#upgrade-centos-6-10-to-centos-7-2-1511

and I am not clear it is a good path to be attempting for LXC Container. The focus here seems to want grub files, and config, which are not apparently present inside an LXC CentOS instance by design/intent.

So. Kind of curious if anyone has suggestions such as
-- here is good way to do an in-place CentOS 6.X to 7.X inside a LXC Container VM?
-- or, run screaming, don't look back?
-- or deploy a newer more current OS LXC VM from scratch, just manually migrate the app/data/config and get on with life? Possibly AlmaLinux 9.X.Latest or something. Or maybe just make the jump to Deb.12.X.Latest and don't fuss about the prior systemadmin who loved CentOS/RHEL stuff.? This is mainly a mule to run a tomcat java app so it is pretty host platform agnostic.

Clearly this host is not exposed to the public, internal use only, etc, hence the stale platform that 'works fine for now, we can upgrade it soon, honest we promise' kind of situation. Sigh.

Any thoughts, comments, suggestions, etc are most welcome.
Thank you!

Tim
