Hi TA,
The steps are different depending if the server(s) are defined by IP address or Hostname
but all the steps are here

If you are talking licenses then you must be running in a virtual environment. If so,
you will have a 30 day grace period to get the license updated:
License Files and License MACs for Cisco Unity Connection Virtual Machines
Each license file for a Cisco Unity Connection virtual machine (except for the demonstration license file) is registered to a license MAC value. This value is calculated to look like a MAC address based on the settings listed in Table 42-1, but it is not a real MAC address.
If you change any of these settings, the existing licenses become invalid, and you must obtain replacement license files that are registered to the calculated license MAC value that is based on the new settings. The old licenses continue to work for a 30-day grace period. During the grace period, you can change the settings back to the original values to make your original licenses valid again. If you need more than 30 days of grace period, change your settings to the original values, then change them back to the new values that you want to use, and you will get another 30- day grace period.
If you do not reset the 30-day grace period by changing settings back to the original values, then Connection stops running. If you restart the server, Connection starts running again but stops after 24 hours. Each time you restart the server, Connection runs for another 24 hours until you either change the settings back to the original values or you install licenses based on the new license MAC value.
