So far, so good. :)

No. :) You have to make a standard failover of a single Bacula env when
you'll prepare a DR plan and not force to make a "migration" from one
Bacula env (site A) into a second Bacula env (site B).
What I implement in this case are:
- failover site has an offline installation of Dir + Cat (both services
stopped)
- SD is running as online service as it will receive replication data
(volumes)
- implement a cyclic "rsync" of configuration files (any file replication
method will work)
- implement a standby database on site B (i.e.
https://wiki.postgresql.org/wiki/Hot_Standby)
- run a standard copy jobs from site A into a site B (all information about
jobs at site A and B are saved into a single catalog which is replicated)
the failover procedure goes as follow (could be scripted or performed
manually)
- the plan assumes that site A is no longer accessible and burned in hell :)
- switch standby catalog to a standard one (will require a database
configuration change and restart)
- run all required Bacula services which were offline on site B
- delete all volumes from site A which are no longer available from catalog
(using bconsole) then all your job copies becomes masters
- your site B is now your main and should include all jobs replicated until
disaster
Above procedure was implemented in real world and tested. works like a
charm.
best regards
