I recently did a migration to move our CUCM nodes to be specified by FQDN hostname. We had been using non-FQDN hostnames, however, we wanted to migrate to using the FQDN hostname to line up with current best practices and in prep for piloting Mobile and Remote Access (MRA) on Expressway. In the process of putting together my implementation plan, I realized that we would likely lose any RTMT profiles we had saved which can be quite complicated and have a number of custom counters defined.
Fix existing RTMT profile after CUCM node rename
