Our current Active Directory domain consists of 3 Windows 2003 domain controllers. The FFL and DFL are Windows 2003. In the domain, we have a member server running Exchange 2003 Server for messaging and another Windows 2008 member server running MOSS 2007.
We have been given a budget for an IT refresh and would like to upgrade to the latest versions of these products where possible. I have read various blogs that advise that an Exchange 2003 messaging environment is not supported in a Windows 2012 domain. My dilema is where to start I want to upgrade Active Directory to 2012 and also Exchange to Exchange Server 2013. Is there a recommended approach to this without breaking the system?
Thanks
