I have a domain controller with windows 2003 server and exchange 2003.
If I want to do a migration from exchange 2003 to 2010, I need an internal certificat authory.
Step by step:
- Join new server (windows 2008) on domain
- Install pre requisites exchange 2010
- Install Exchange 2010
But, when and where I must install the autory certificate ? DC under windows 2003 ? new server ?
