[cisco-voip] Migrating from CM 4.1.3 to Cisco BE 7.0

[Justin Steinberg]

Keep in mind Wes always sees the problem childs... :)

I've done many 4.1 to appliance upgrades including some with AD integration
and have never had any significant problems.  I've had to deal with some DMA
warnings but I can usually work them out.

That being said, I would definitely run DMA well in advance of your upgrade
to make sure it is completing successfully prior to your upgrade window.
You can then rerun DMA during your upgrade window to get a new current copy
of the 4.1 DB and use that for your upgrade.

BAT can export some phone data, but you'll lose things like ccmuser speed
dials, pab/fd, etc - one of the reasons I always try to use DMA.
