I have an exsting BCM 400 & BCM 450 working with codes loaded. The customer is shutting down the 400 location and moving the people to the 450. Can I get the codes from the 400 and move them to the 450? Is that just like when you actually upgrade and just get a migration code or are there other steps I need to look at. I know either way I have to send the MSC card back and I get a clean one with no codes on it.
