I have read in many of the technet articles that Exchange 2010 and exchange 2007 can coexist in the same organization. Here is my scenario:
1 existing exchange 2007 server in a single active directory domain on windows 2003 r2 server
1 new exchange 2010 edge transport setup in a workgroup in the dmz on windows server 2008
I would like to use the exchange 2010 server with the edge tranport role servicing the exchange 2007 Mailbox/hub transport server.
Exchange 2007 is running SP1 but later today I plan on upgrading it to SP2.
First I want to know if this scenario can exist, from everything I have read they can coexist together. Secondaly, I am getting an error when I try to import the edge subscription file into the exchange 2007 server.
"The version of the edge subscription doesn't match any hub transport servers in the subscribed site"
The edge is in a workgroup and when I do an export of the edge subscription this is the command I ran:
New-EdgeSubscription -FileName "C:\EdgeSubscriptionInfo.xml"
I never specified a AD site name, could that be the reason why? Wasn't sure what the exact syntax was.
I have verified the time on both servers is synched and name resolution is working properly.
I am working with a deadline so if this doesn't work i may have to uninstall ex2010 on the new edge box and install ex 2007.
