I have windows 2008 server with exchange 2010 SP3 I am trying to upgrade to another box which has windows 2012 with exchange 2013. when I it do the prerequisite to install exchange 2013 I get this error.
All Exchange 2007 servers in the organization must have Exchange 2007 SP3 or later installed.

The problem that I don't have exchange 2007 on my organization. maybe I am not sure that exchange 2010 was loaded on exchange 2007 I am not sure.
how I get rid of that.
