accidently upgraded to 6.3 buster from 5.1 stretch

[teddyh2o]

accidently upgraded to Proxmox 6.3 buster from 5.1 stretch without following the procedure.
the end user used

deb http://download.proxmox.com/debian/pve buster pve-no-subscription

on stretch.
i changed the repository to stretch and try to install proxmox-ve but getting this error

Reading package lists... Done

proxmox-ve is already the newest version (6.3-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

i know this is a stupid user error but is it possible to reinstall/download to 5.1 or 5.3?
currently, pveproxy and pvedaemon are unstable to start

The Proxmox VE 5 repositories are still available, so you should be able to install the packages on top of Debian Stretch.

i know this is a stupid user error

Proxmox VE 5 as well as Debian Stretch are at end of life. Therefore upgrading is strongly recommended.

It seems you have packages from both PVE 5 and PVE 6. For example, libpve-apiclient-perl 3.X is from PVE 6. Depending on the complexity and requirements of your setup, it might be less headache to create a fresh installation (directly with PVE 6?) and restore backups.
