As Christian said offline work on the catalog goes over security, so you find agents. What you don't know if they are really active or not as that depends on the entries of the scheduler, and that list you can get it from the database (if an agent isn't active and scheduled you don't care as the migrated state will be the exact same one: an unscheduled agent).

If you query the agents tables in your BIPLATFORM schema (the one created by RCU) you can get the list of agents enabled and scheduled (and because in a table you also get the path you can see if they are in /shared or in a user folder and can easily make a list of the users to inform with the info about the agents).
