I am looking for the best alternative going from exchange 2003 Standard to Exchange 2013. I bought a brand new Dell Server to install Exchange 2013. I have an existing Exchange 2003 running in a 2003 AD domain. I know Exchange 2003 and 2010 can co-exist and is a viable upgrade path, and then upgrade from 2010 to 2013. However, none of these options are in-place solutions. So, if I first upgrade from Exchange 2003 to 2010, how will I then upgrade from 2010 to 2013 without another server for the Exchange 2013 implementation?
I understand I can completely remove the existing Exchange 2003 server, and then install Exchange 2013 on the new box. However, I have heard completely removing Exchange 2003 from AD domain is problematic and a headache. We only have 15 clients so we are not talking about a big installation. I prefer making one move from 2003 to 2013, but I like the migration option going from 2003 to 2010. Any suggestions?
