[cisco-voip] Direct Upgrade using DMA

[Matthew Loraditch]

The physical servers don't matter at all, I went from 7815 models to the 3rd party hps equivalent to 7835s with no issues

Good Moring

I have a PUB and a SUB on 4.1.3(6) and we are going to migrate to CUCM 7 (probably 7.0.2).

I would like to get 2 new servers and place them in my lab, upgrade on those servers and then just install them into production once I have all the bugs and gotchyas worked out.  My account team is telling me the servers I buy have to be EXACT matches to the ones I have in production today.  This is disheartening since I would like to upgrade from 7835 to 7845's as part of this process.

Are they feeding me a line of *$&%^ or are they right?

Thanks

Kevin
