Currently I have Windows server 2003 Active directory domain. It was upgraded from windows server 2000. Also mail server is Exchange 2007 standard.
I wish to upgrade the domain to windows server 2012 and to exchange 2013.
I may still be running old windows server 2000 and windows server 2003 machines.
Please let me know if there will be any issue with this upgrade to these machine. Is windows 2000 and windows 2003 server are compatible with 2012.
