Question Debian 12 to 13 Dist-Upgrade

[hschramm]

Server operating system version

Debian 12

Plesk version and microupdate number

18.0.78#2

Hi folks,

Debian 12 (Bookworm) looses regular updates on June 10th, 2026. Till now I have not found any dist-upgrade possibilities from debian 12 to 13. On the roadmap page they aren't even planned. I know that the current "idea" of plesk is to migrate from debian 12 to 13 via reinstalling and migrating. But: I have over 100 servers to migrate, which would mean, that i have to create the current infrastructure as duplicated one and move over.

How do others this? Do you really migrate manually all data to new machines? What is planned from PLESK side about this topic?

Kind regards,
Holger

Hi, Holger. Our team is currently focusing on the dist-upgrade script for Almalinux and Ubuntu. Once completed, they will start working on a dist-upgrade script for Debian. I am afraid, I cannot provide an ETA at this moment.

For completeness' sake it might be worth pointing out that Debian 12 moves to TLS branch starting June this year and will continue to receive TLS support till June 2028. Which coincides with Plesk's support for Debian 12.
