Really?!?! Dang... I have been away from these things for too long. We used to support ~100 of these years ago, I think we have less than a half dozen left, and just lost another one. Only touch them a few times a year these days. 98% of all the telephony work we do these days is with our hosted product.

Yeah, same here really, a dwindling number of MiVB customers left, basically only customers who are too indecisive to do anything!

Sorry but no intention to hijack this thread. Just that topic is related to my question. But what would be the best way to migrate (replace) MiVB using an old CX controller to EX + AG41XX? I don't know the version of the current system running on the CX but I'm assuming it is old.
My training only started from V10.0 and I'm only familiar with the VA, EX-Controller, and SMBC Controller.
Is it possible to take an backup from the CX system and import that into the new MiVB on EX for a baseline to re-program?
Dogbreath:
Migration Guidelines document covers this scenario I think:
