Unusual situation here, hopefully someone can help.
I work with a vendor, and one of our customers has a 4.1(3) CM cluster. After taking on their business, they purchased an upgrade to 7.0(2). However, their configuration is uniquely awful and only semi-functional. The dial plan is a disaster.
As part of the upgrade, this customer is purchasing all new server hardware. Is there some way that we can successfully execute this upgrade without having to run the DMA tool on their existing Windows servers? DMA provides DLU licensing as well as configuration data, but the configuration data is next to useless, and is nothing we can't get by directly accessing the CM database anyway. Are upgrade DLUs available any other way?
