Upgrading to Succession 4.00t and CallPilot 3.0 ??

[MechDriver]

I'm going to be performing an option 11c upgrade from 2111 rel.22.16+ to Succession 4.00t and MerMail 12.12.7 to CP 3.0.
I have been led to believe that succession 4.00t won't support MM and must be changed to CP. If this is so, will 2111 support CP? which end do I upgrade first. btw I will be using data migration on the MM to CP. Also this is a live system on the customer site. They are expecting everything to work in the morning.
Anyone faced this issue before?

Thanks for you input.

Mer mail 12.12 - 13.14 is supported on rel 4!

I would upgrade the PBX first, the voice mail is just a feature, who cares if it works but the PBX doesn't lol

Meridian Mail 11 is still working on Rls 4.00T...
Nortel says that it's not supported only because they don't test it...and wants to sell CP

Upgrade the PBX to 4.0 first. Following that, as long as you have the space available in the PBX, I'd suggest installing the CP along side the MM to start. You can get it up and functioning prior to the migration, allowing you time to test it and "burn in" the system prior to shifting the customer live on it. Just use a new ACD queue for the CP and a temporary CDN. Also, create the DN of the ACD queue for MM in the SDN table for CP, so it's already in place without requiring another run of the Configuration Wizard when you move out the MM. When you're ready to do the migration, out the ACD queue for the MM and rebuild it as a CDN for CP.

If the customer doesn't have a really big reason they want to migrate from MM to CP, I would strongly suggest using this opportunity as a spring cleaning for the MM(especially considering the vintage of it). Unless the customer is VERY dilligant on maintaining the users on the MM system, they will be migrating over potential non-used mailboxs(ex-employee's, phones, et al). Also, since you will have to recreate the Voice Menu's using Application Builder, it's easier to get that all setup ahead of time without being pressured to try and get it done in one night. By putting the system in clean, it should provide the customer with a better starting point to maintain the system then by carrying over potential wasted space(although at least with users, it is alot easier for them to look through CallPilot then it was in MM).
