[cisco-voip] About DMA // Upgrade from 4.1 to 6.1

[Jonathan Charles]

Haven't had to do that....

Every time I have had replacement servers, I have always been a fan of
replicating the existing version on one of them (say 3.3(5)Sr2 or
whatever), restoring the customer's backup, upgrading to 4.1(3)sr5d
then installing DMA and running it... all on an isolated VLAN.

This way there is no concern about screwing with their existing
server; also gives us a really clean backout (just swap the ethernet
cable back...)
