Change CUCM IP Address Without License Re-Host

Hello this post is about how to change the CUCM IP Address without request a license re-host from Cisco Licensing Team, It only covers the process for Publisher when it is defined with an IP Address (when it is defined by name the process is very similar, but take care with DNS resolution).

For this Lab I´m using Communications Manager version 9.1.2, my LMS is the same CUCM.

1.- Take a DRS for all your servers, for example CUCM, CUC and IM&P.
2.- To avoid issues related with ITL file set the "Enterprise Parameter" >"Prepare Cluster for Rollback to pre 8.0" to "True" for CUCM.
3.- Under LMS check your current inventory to reflect the actual status. You can see my CUCM with an IP addres 10.1.X.X.
