So we had a 2003 domain and exchange server migrated to sbs2011, we are now attempting to migrate from SBS 2011 to Server 2012 with Exchange 2013.
SBS 2011 has SP1 installed
Exchange 2010 SP3 RU 1 - installed
Forest and domain 2008 R2
No Edge Servers
Here's our problem:
Exchange 2013 does not recognize that exchange 2010 SP 3 is installed.
Does anyone know why it does not see that exchange 2010 SP3 is installed, let alone even after RU 1 has been installed as well?
Many thanks for the help.
