Google apps and exchange question

[danpitman2]

Hi

 

I am in the middle of planning a move from exchange 2010 to Google Apps

 

I have provisioned all the users using GADS and have GAPS setup to sync all their AD passwords

 

My question..

 

I want to transition students to using Google Apps for Mail before staff without migrating any existing emails, my problem is with the current distribution lists we have for our year groups in exchange, all our students have a .students.schoolname.net address and staff have schoolname.net address so moving the students would just mean changing the MX records for students.schoolname.net to Google so it starts to route mail to Google, but what if a member of staff who would still be using exchange and outlook needs to email a student or a whole year group, as exchange would still think this is internal and still route to their exchange mailbox, how would I change it so it knows students.schoolname.net needs to go external instead?

 

Many thanks
