I have an existing 2003 AD domain with Exchange 2003 (2 domain controllers and 1 exchange server). I have new physical servers to upgrade/migrate to. The new servers are Windows 2012 and Windows 2012 with Exchange 2013. Is there a direct migration path I can follow? Do I need to use an intermediary 2008 Server? I ask because it appears that Exchange 2003 is not compatible with AD 2012, and Exchange 2013 is not compatible with AD 2003.
After some more searching it looks like the best plan is to use an intermediary server for exchange. Start with AD 2003 and Exchange 2003. Migrate Exchange to 2010. Migrate domain to 2012. Then migrate Exchange from 2010 to 2013. Does this makes sense? Is there a better way to do it?
