I am currently migrating a Unified CallManager cluster 4.2(3) to Unified Communications Manager 6.1(3) during this process I receive the following output:
There is a mismatch between the ServerName 172.20.3.240 in the DMA File (Windows DB) and the IP address 126.96.36.199 of this machine. Install will remap the ServerName 172.20.3.240 to 188.8.131.52
I have read through the documentation and understand that due to the reconfiguration of the ServerName to IP address that this message will occur, remove DNS reliance. What I cannot understand is 184.108.40.206 is my FTP server address which has never been configured in the CallManager database?
If I select proceed the migration is successful and the first node has the correct IP address of 172.20.3.240?
