We plan to upgrade CUCM Thursday morning during the maintenance window.
Moving from 7.1.3 to 7.1.5
The upgrade is necessary for the CUCM to function with the new routers purchased to replace the old 6503 switches.
There should be no outage or effect on users, with one potential exception, the Auditorium Ticket Office ARC Attendant Console may need to have a service restarted after the upgrade.
Prep work will occur today, again this work should have no effect on users.
