I am currently running Exchange 2003 running on Windows 2003 migrating to Exchange 2010 on a Windows 2008 R2 server. The connection is working between the two systems. The problem is the 2008 r2 server is having problems and I need to rebuild and I don't want to lose all my configuration or data. How is the best way to back up and move to a different server and not lose anything. I have Symantec 2010 if that helps.
