Migrating from Exchange Server 2003 to Exchange Server 2010: A Small Organization Perspective

Two things.

1. After following your guide my 2003 server stopped sending email out. In addition, any email sent to my 2003 machine where a user was on the new 2010 machine, didn't get their emails. Everyone got stuck in the queue. After an hour of reading the MS website I found a page that told me to run:

New-RoutingGroupConnector -Name "Interop RGC" -SourceTransportServers "Ex2010Hub1.contoso.com" -TargetTransportServers "Ex2003BH1.contoso.com" -Cost 10 -Bidirectional $true -PublicFolderReferralsEnabled $true

Right after, all unsent mail got sent. I have a single Exchange 2003 setup and am moving to a single 2010 setup. Something in your guide is missing. There is NO routing between the two servers from following your guide.

2. Set-OWAVirtualDirectory Clark2008\OWA* ` - that means nothing to me. What is Clark2008? What are we looking to put in there ourselves? Either way I dropped it. I see no reason to run the legacy stuff at all. Until the new server is fully functional, we simply have two mail servers addressable from the outside. No big deal.

All in all, thanks for the guide! Aside from that one hiccup, it got the job done. Two hours of downed email...blah, they can deal with it! :)

Since our organization is only running an Exchange 2003 SP2 server and no Exchange 2007 servers I assume it's ok NOT to install the KB937031 Hotfix?
