That's pretty much it.  Make sure you power down the server prior to  
removing the 4.1 disks.

If we had to fall back to 4.1.3 by reinstalling the 4.1.3 disk drives  
do we need to do
anything  special or is it simply a matter of powering down the Call  
Manager servers, removing the 6.1 disks, inserting the 4.1.3 disks  
and powering the servers up? I have tried this in the lab and it  
seemed to work fine but I just want to make sure I am not missing  
anything.

Thanks!
