CUCM Changing OS Admin Username before upgrade to 15.x

[Michael.Blum]

Hallo at all and best reguards from Germany

A UC Cluster has difference OS Admin Usernames.
I want upgrade this UC System from 12.5 to Version 15 with PCD.
I have now added an additionel OS Username with the same Name how the other has.
The new User has not all tghe privieleges as the default User.

The Question is:
Can i update the System with PCD with the new OS Admin User and the privileges or will the System hang up while the update

and

can TAC change the default OS Username ?

Thank you very much.

Michael

It can only be set at install time. A PCD migrate job can do it though since it uses new VMs.

Sort of related, but not an exact match. The name of the user can be changed with this command, utils reset_application_ui_administrator_name.
