Migration to Windows 2000

I looking to migrate the contents of an NT 4.0 PDC, to a brand new, more robust Windows 2000 DC.
This box currently houses Exchange server 5.5 on it as well which will also be upgraded to Exchange 2000, any words of advice would be appreciated.

The best way of migration - install one bdc in your domain, synchronize it fully with ur pdc and take it offline. Now upgrade ur pdc to w2k server and after installation run dcpromo command, it will migrate all ur previous user account to newly installed server.
Before upgradation take the full backup or make image of ur hdd using ghost and check whether ur hardware and applications ur runnining are fully compatible witk w2k using command winnt /checkupgradeonly. I f u don't have device drivers for win2k arrange them first

The only way to migrate an NT4 domain to Win2K is to install Win2K and Active Directory (AD) on an NT4 PDC. It can not be done on a BDC.

It sounds like you want to move your Domain controller function to a new computer. The following assumes that you want to retire your present server.

You have 2 options.

Option 1: On the new computer, install NT4 as a BDC, synchronize with the current PDC, and then promote the BDC to PDC. Install Win2K and AD on the new PDC. All user accounts will be migrated.

Option 2 (less work - more chance of problems): Install Win2K (and AD) on your current PDC (if it meets minimum requirements for Win2K). All user accounts will be migrated. Promote new server to DC. Force replication of AD data. Transfer all FSMO roles to new server. Demote old server.

Exchange: Exchange 2000 must be installed on Win2K server.

Using option 1 above: After migration to Win2K is complete, install Exchange 2000 on the new server as an additional server in your present Exchange site. Migrate all mailboxes from the old server to the new server.

Using option 2 above: follow same process.
