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 18.104.22.168 of this machine. Install will remap the ServerName 172.20.3.240 to 22.214.171.124
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 126.96.36.199 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?
The version 4.2(3) servername was configured to an IP address to remove DNS reliance 172.20.3.240, the hostname was BHO-PUB.
During the installation of CUCM 6.1(3) the hostname was configured to be BHO-PUB with an IP address of 172.20.3.240, the same address as before. Yes the mismatch was reported during the DMA import. The DMA file is stored on a server 188.8.131.52, using FTP to transfer the file. My confusion is why would the DMA refer to the FTP server's IP address for remaping.
The cluster is up and working with no apparent problems.
