We have a massive SharePoint 2007 intranet web application that consists of 60+ site collections. Our plan is to set up a SharePoint 2010 web application, then move the site collections over one by one, by backing up their content DBs, restore them to the backend DB server for the 2010 application, run the pre-upgrade checker on them, then join the DBs to like site collections.
The issue is our email enabled document libraries. On the incoming email settings for the 2007 server farm, we have the addresses set up as "@yyy.zzz.com". We have email enabled doc libs set up over many of the site collections. We have Exchange Server forwarding emails from group mailboxes, and SAP applications sending automated emails to these libraries.
So my questions...
Can I set up my SP 2010 farm to use the "@yyy.zzz.com" addresses? I'm sure the answer to this is Yes, but this is a good starting point.
Can Exchange Server recognize where emails with @yyy.zzz.com addresses are supposed to go, when I move their associated doc libs / site collections from one farm to another?
What sort of steps would I have to take to enable this?
I asked this of our Exchanger Server admin, but he did not have an answer.
