Microsoft Exchange Server 2013 Setup can’t continue because it detected one or more Exchange Server 2007 servers haven’t been upgraded to Exchange Server 2007 Service Pack 3 (SP3) Roll Up 10 (RU10). Before you can install Exchange 2013, all Exchange 2007 servers in your organization must be upgraded to Exchange 2007 SP3 RU10. This requirement includes Exchange 2007 Edge Transport servers. For more information, see Upgrade from Exchange 2007 to Exchange 2013.

After you upgrade your Exchange 2007 Edge Transport servers to Exchange 2007 SP3 RU10, you must re-create the Edge subscription between your Exchange organization and each Edge Transport server to update their server version in Active Directory. For more information about re-creating Edge subscriptions in Exchange 2007, see Subscribing the Edge Transport Server to the Exchange Organization.
