[cisco-voip] DMA 4.2 to 6.x staging !!!

[Kevin Thorngren]

This describes one of the problems that can be encountered with an  
underscore in the hostname:
http://www.ciscotaccc.com/kaidara-advisor/voice/showcase?case=K40221577

Although I have not tried this myself the 6.1(1) upgrade  
documentation states, on page 20-21:
"This feature allows you to import your 4.x data to a 6.1(1) server  
without having to preserve the IP
Address or Host Name. The IP Address and/or Host name of the 6.1(1)  
server can differ from the 4.x
servername. "

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/upgrade/6_1_1/ 
upgrd611-pdf.pdf

Due to the rules built into DMA I would suspect, although I don't  
have documentation to back it up, that any non-DNS supported  
characters will be flagged as an error.

Do you remember if the hostname or IP Address was configured under  
System > Server?

I am note sure if DMA performs the hostname check against the actual  
hostname or what is configured under System > Server.  Based on  
looking at some DMA logs I can see that DMA does keep track of the  
actual hostname, Ip Address and System Server hostname/IP.
