Question
Does Plesk support Debian 13 (Trixie)?
Answer
Debian 13 (Trixie) is supported starting from Plesk Obsidian 18.0.74.
Known limitations
Dist-upgrade from Debian 12 to Debian 13 is not yet supported by Plesk. The recommended way to switch to Debian 13 is using Plesk Migrator. Support for dist-upgrade and/or dist-upgrade CLI helper will be added later.

When will the dist-upgrade from Debian 12 to Debian 13 officially be available?
I have successfully upgraded a test VM some months ago, so this shouldn't be too hard.
I was hoping with the 18.0.77 update that we would have dist-upgrade from Debian 12 to Debian 13. Please make this available ASAP.
If, instead of upgrading, I have to migrate, I will - away from Plesk.
I hope the Debian 12 to Debian 13 upgrade path will be available soon. Debian 12 has several known issues that are resolved in version 13, so making this upgrade available as soon as possible is critical. A migration is not an option in my case. I would appreciate swift support regarding this upgrade process.
Also waiting for that migration script. Could you please give your paying customers give an ETA on this!
Is there already an ETA on the Upgrade to Trixie?

When is the dist-upgrade from Debian 12 to Debian 13 supported by Plesk?
Hello guys,
I asked Plesk for a better answer on this page.
Here is their answer :
> Hello Charles,
Please note that our Developers Team is working intensively on dist-upgrade tools and solutions this year, although the priority is driven by audience being Ubuntu the most used, the support and process for Debian 12 to 13 upgrade will be done before the end of this year.
As soon as we have a more precise ETA I will share it here by updating the article accordingly.
In the meantime, in order to switch from a Debian 12 server to Debian 13 please consider the migration alternative.
Thanks for your understanding and patience.
Cheers.
