samba - Nov 2025 - Upgrading Samba AD DCs from Debian 12 (Bookworm) to Debian 13 (Trixie)

It will be easier, safer and future proof.

These notes are valid for Trixie except the backports.

Hi Luis, Rowland, and Carlos, 

We are in the same situation than
Carlos, we host self-compiled samba4 on Debian virtual servers. 

We use
to simply upgrade our DC the way Carlos reported, and generally, to run
the compilation again. 

Should we expect any particular issue with this
upgrade or you think this steps should work the same way ? 

To be
honest, promote/demote is not really an option since the hostname is
used in many third-party scripting, firewall configurations, and so
on... 

Thanks,
