In our config files our condor host is referred to by using a hostname
that maps to a CNAME entry, rather than the "real" name of the machine.
When we upgrade our central managers we just get new ones up and running and tested,
then change the CNAME entries to point to the new CMs. If there's any issues we can
easily roll back to the old CMs by changing the CNAMEs again.
This assumes you have control of the DNS servers for your location, or at least can
work with those who do look after your DNS info.

The other option is to set up a new pool with the new master and migrate
worker nodes one by one.
