I have a single server running Windows 2000 Server-SP4 with Exchange 2000-SP3 (100 mailboxes) and I am replacing that with a new box running Windows Server 2003 and Exchange 2003. The tricky bit is that we are moving to a new domain name, reason being is errors made before me, our current domain name is the same as our external domain name, eg. domain.com.au is our internal domain name also instead of HeadOffice.domain.com.au
As I don't want to have to recreate all of the AD and Exchange users again and export/import PST files, what are my options (I am not keen on adding the new server to the existing domain, going through the demote/promo and then later the 80-page document on changing the domain name)??
This work will be done over a weekend, and the existing server has to be up and running till the start of that weekend.
