Downgrade from bullseye to buster

[dfwplay]

I fubared my pve 5.4 setup by upgrading debian from buster to bullseye. Not sure how to recover. Downgrade back to buster or upgrade pve to 7.x. I have working containers I need to recover. any help or walk through would be greatly appreciated.

How do I backup my CT's.
my /etc/pve directory is empty

There is no easy way to downgrade. Best you backup the PVE host before doing a major version upgrade. And always having recent VM/LXC backups should be taken for granted.

my /etc/pve directory is empty

You need PVEs cluster service running or your PVE configs won'T be mounted as those aren't simple files on the root filesystem but stored in a SQLite DB: https://pve.proxmox.com/wiki/Proxmox_Cluster_File_System_(pmxcfs)

Update:
I was able to downgrade Bulleye to Buster using this guide
