[HTCondor-users] Upgrading old Condor pool to modern times

[Szabolcs HorvÃtth <szabolcs.horvatth@xxxxxxxxx>]

Hi,

We will upgrade our legacy but working Condor pool setup from using 8.4.5 to 25.2. Instead of trying to migrate all the legacy configurations and attributes, we'll start mostly from scratch.
Are there any known issues, things to look out for when doing such a big leap in the Condor lifecycle? Were there typical issues that admins faced when upgrading between major versions?
(Both the central manager and the startd machines are on Ubuntu 24.04.)

Cheers,
Szabolcs
