migrating a customer from a 200ICP to a 5000

[RossBC]

we have been a 200 and 3300 dealer for years. we have just taken on the 5000 line and are soon to do our first "upgrade" from a 200ICP to a 5000 re-using the 5212 and 5224 sets. have gotten good at telling the customer what to expect when going from a 200ICP to a 3300, but have nothing on this migration.
Does anyone have a list of expected differences? I can see it will be quite long as HOLD is about the only feature that works the same and was hoping on a head start.
thank you very much for any insight. I will be posting in other forums and will update all with my compiled findings.

Wow... you seriously don't know what you are in for.

The comparison is very difficult to make, since you are talking a pure PBX (SX200) to a Hybrid Key System, it is literally night and day. I would seriously suggest getting some training from Mitel, the familiarization and end user training plus the regular technical training... seriously, I don't even know where to begin to give you a comparison and I have been using and installing the 200 for over 20 years, and the Axxess/5000 platform for a good 10 years.
