First step for migration to Debian Trixie is to upgrade HAProxy to version 3.0 on all cache hosts to ease migration to the same version on Trixie.
This means checking the repository, configuration validity and eventual migration from 2.8 to 3.0, testing on canary hosts and complete rollout.
Roll-out status:

| Resolved | Fabfur | T417253 Upgrade to HAProxy 3.0 on cache (bullseye) hosts |
