Hi guys, I need your help with this. I will be upgrading a system that is currently a MICS 4.1 CDA XC. Our company had ordered a DR 7.0 software but what I have is an upgrade toolkit for MICS 7.0 CDA XC. Will this work? I read somewhere that there is a different upgrade toolkit for a DR 7.0 Software. If so, should we just purchase an upgrade toolkit for a DR 7.0? But won't I have a problem since we are going from a 4.1 CDA XC? Or should we have the DR 7.0 replace with 7.0 CDA XC? The customer has no companion phones and is just mostly digital and analog trunks with Norstar Voicemail with Cimphony software that will also be upgraded.
