You can safely backup and restore as long as the major version is the  
same.  So a backup from 4.1(3) should restore just fine to a 4.1(3) 
SR5 server and vice versa.

As for your subs once the pub is done just install them from  
scratch.   The good thing about migrating to new hardware is that you  
will have plenty of time to install and test to make sure you have  
the process down.

I have a CallManager 4.1(3) cluster that I need to migrate to new  
servers as my current servers are EOL. I do not want to upgrade at  
this point in time due to some third party compatibility problems.  
The current cluster currently has SR3C installed, so I'm not sure  
what my process for migrating should be. I assume that I have to  
install SR3C on the new publisher prior to running the BARS restore,  
but then  I wasn't sure if the subscriber would install properly with  
4.1(3) given that the publisher already has a SR installed. Am I  
going to run into any issues? Is there a better way to do this?

Thanks,
Adam
