Converting Avaya PBX or CM PBX's with SCC1 or MCC1 Media Gateways to Avaya G650 Media Gateways

As an Avaya Certified Expert working with Avaya products (but non-Avaya Employee) I'm asked questions all the time pertaining to solving issues with Avaya products. In the interest of promoting Avaya products and services and thus improving the stance of the company that makes, what I feel is the most feature rich and stabil, IP enabled, PBX on the market; I am providing my answers to such questions to users of Avaya products...

A user asked:

"

Current setup is CM3.1 8500 with SCC stack. I want to swap to G650s. Before changing cabinet types can I leave everything in slots 2 through 14 programmed? Or do I need to xport all stations and pull out ds1's etc.

My suggestion:

To change a cabinet type in Communication Manager software you must remove all cards and the translations on those cards. You can't leave anything in or you won't be able to run the "change cabinet 1" command successfully. If you have access to ProVision this can be done easily and most of the stations will be able to be changed with ASA using an import or find and replace function too.

This is common with an upgrade; you must always remove all the ports and translations pertaining to any cabinets you are changing or upgrading to a newer model.
