We have a customer want to upgrade their Exchange to 2007 , currently they have Unity 4.2 Unified messaging with exchange 2003.
Since they bought new servers, customer wants to know if we install a new Unity 7.x server with same Exchange 2003 partner server as Unity 4.x and want to know if there are any issues
1. On Unity server if they move subscriber from Unity 4.x to 7.x. I think we can do this with digital networking and GSM without any impact to users correct?.
2. On Exchange side later when they move the same MBX from Exchange 2003 to 2007 will there be any impact to subscriber.Do we have to do anything on Unity ?
Both Exchange will be on same AD, same exchange domain.
Thank you so much for your help.
