We have installed windows 2003 R2 SP2 in one of our server and installed ISA 2006 role in that server. Which is working properly now. since Microsoft was stopped security patches for windows 2003 we may need to go with windows 2008 or 2012.
Please any body help me to migrate the OS with affecting our the ISA 2006 configurations.
awaiting for your valuable reply.
