I have an HP server that has Microsoft Windows 2000 server installed. I need to upgrade it to Microsoft Windows Server 2003 64 bit edition. It is running Exchange 2003 and needs to be moved to Exchange 2007 which I understand I can't do without moving the the 64 bit version of Windows Server. <br />
<br />
Can I do a simple upgrade from 2000 32bit to 2003 64 bit? I have spoken to a few people and they have told me that it is not possible, that I would need to format the computer and reload the 64 bit version fresh.<br />
<br />
I need some help! Thanks in advance.

Upgrade from Microsoft Server 2000 to Microsoft Server 2003 64 bit

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
