writing to inquire if anyone has had to change the IP address of the Call Manager with a IPCC Express 4.x server on the network? I have a customer who wants to move thier CallManager (UCM 6.1) but I am not 100 percent sure on the impact on the IPCC Express Box.
To be more clear my question is what are the area of IPCC Express that I need to change i.e. registry settings etc.
there is a number of steps you need to perform BEFORE actually changing the IP address of the CallManager server within the IPCCX configuration.
There is a tool called CRS Serviceability Utility, you can find it in the Start menu on the IPCCX server.
Make sure you plan a maintenance window because this operation needs a CRS node restart.
Take a look at two panels, Cisco CallManager IP address and the CiscoCallManager LDAP configuration (if you use the default LDAP server, "DC Directory").
Take a look at the attached screenshot.
