My upgrade was fine some things I noticed.
Note: I only updated PVE not ceph to newest version.

Problem: Error on apt update
Cause: You might still have pve non subscription or pve-enterprise repository active
629 packages can be upgraded. Run 'apt list --upgradable' to see them.
W: Skipping acquire of configured file 'pve-no-subscription/binary-amd64/Packages' as repository '
http://download.proxmox.com/debian/pve bullseye InRelease' doesn't have the component 'pve-no-subscription' (component misspelt in sources.list?)
W: Skipping acquire of configured file 'pve-no-subscription/i18n/Translation-en' as repository '
http://download.proxmox.com/debian/pve bullseye InRelease' doesn't have the component 'pve-no-subscription' (component misspelt in sources.list?)

http://download.proxmox.com/debian/pve bullseye InRelease' doesn't have the component 'pve-no-subscription' (component misspelt in sources.list?)
Solution: comment out non-subscription under /etc/apt/sources.list and enterprise repo unter /etc/apt/sources.list.d/pve-enterprise.list and run apt update again ;-)

Problem: no storage-migration after upgrading the first host (mellanox 25gbit connect-x5)
Cause: ceph network down (ssh: connect to host 10.100.100.231 port 22: No route to host)
Reason: naming of interfaces changed
Details:
ens5f0 changed to ens5f0np0 resulting in no ceph network after upgraded
ens5f1 changed to ens5f1np1
Solution: changing the slaves in the bond1 to the new names

Problem: error installing grub on devices
Cause: you might use systemdboot (UEFI), check IF you dont know
Solutions: skip error and reboot after upgrade, my machines bootet fine
