Many components of the Error Tracker need to be made aware of the new release.
The retracers need to have a configuration in ./src/retracer/config. See

There are still many places where the series are hardcoded. While an effort is
ongoing to change that, the best that can be done for now, is to search the repo
for both previous series codename (like questing) as well as version number
(like 25.10).
In addition to changes to this repo, all the deployment machines need to be
updated with the SRU'd distro-info-data. This should in principle be automatic
if some sort of unattended upgrades are configured, but better double check as
all is currently under change, and still has a lot of legacy.
Here is some archive documentation for you. New and up-to-date one hasn't started yet, but the old things are still pretty much accurate, except when it comes to deployment and infrastructure.
