Unity 3.15 in mixed mode(Exchange 5.5 & 2000)

I have a Unity 3.15 server that is connected to an exchange 5.5 server. We have added the Exchange 2000 in mixed mode. I want to start to move users over to the new exchange 2000 server. What do I need to do to re-point Unity to Exchange 2000 and still support users on both. Several thousand mail users to move so it's going to take awhile and I need Unity to support users on both 5.5 and 2000. Also, what's needed once all users are off 5.5 and I'm ready to disconnect it? Thanks in advance...

Re: Unity 3.15 in mixed mode(Exchange 5.5 & 2000)

Assuming the ADC has been set up correctly and E2K is happy, here's the procedure for Unity...

As far as de-commnisioning the E55 server, there's a few articles on Microsoft's web site. One thing that you might run into is CSCea69260 (any mailstores from the E55 server might still have records in Unity's database). It's really a cosmetic thing, but if you do run into that, you can just delete those entries from the mailboxstore table in SQL (after backing up the UnityDb first of course : )
