Your best bet might be to hire a consultant to take care of it for you. Here for something as small as 12gig it would take under 5 hrs at $150 an hour, fairly inexspensive upgrade. Exchange Server 2003 is supported in the following Active Directory environments: * Windows 2000 mixed mode domains * Windows 2000 native mode domains * Mixed Windows 2000 and Windows Server 2003 domains * Windows Server 2003 native mode domains * Windows Server 2003 interim mode domains George Taylor Systems Programmer Regional Health Inc. _____ From: Dave stevens [mailto:london31uk@xxxxxxxxx] Sent: Monday, April 02, 2007 2:43 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Exchange 5.5 standard to Enterprise upgrade OK, so I have not gone down this route simply because the customer can not get hold of an exchange 5.5 enterprise media. I did the long process of archiving mail and doing a defrag. This worked cos I claimed bak about 4gb. this should carry us for about 2weeks. The issue now is that thier current environment is Windows 2000 AD mixed mode My question, can I install exchange 2003 onto windows 2000 AD mixed mode and then migrate the mailboxes over. I guess this would be the easiest way forward ? Any tips would be great, including whitepapers.
