UPDATED: November 14, 2017
Please go to C:\Program Files (x86)\PBBI CCM\DOC1\Designer\Client and C:\Program Files and (x86)\PBBI CCM\DOC1\Designer\Server , you have a file named processor.DLL as an XML file.

Keep a backup of old copies.

Open the files in textpad and change all the references of the old host name to the new name. 


Restart all services.
