[Samba] Need to upgrade to latest samba -> Any caveats?"

[Marco Shmerykowsky PE]

I need to upgrade from Debian bullseye to
Debian Bookworm.  I also need to bring samba
up from 4.17.12 to I guess the 4.20 series.

Typically I haven't had problems in doing upgrades
and I haven't spotted anything in the release notes

I'm currently using the samba backports.  My
understanding is to remove backports from the sources
list before upgrading to bookworm and then adding
it back in and upgrading samba at the end.

Are there any special gotcha's or caveats that
I should be aware of that aren't obvious?

Thanks
