Migration from Exchange 5.5/NT4 to Exchange 2000/W2K orExchange 2003/Windows 2003 Server

  Hello,

   My compagny is upgrading it network from NT4 servers to Windows 2K and 2003, and I'm wondering about the Exchange server... It is actually a NT4 server with Exchange 5.5, and I'd like to now what is the better way to upgrade between Exchange 2000 on a Windows 2K Server or Exchange 2003 on a Windows 2003 Server...

   Active Directory isn't active yet, but will be soon. I know that there is a patch to allow Exchange 2000 to interact with Windows 2003 Servers...

   So, what would you advise me ?

Thanks for your suggestions.

N.B. : sorry for my bad english, but I'm french...
