Upgrade Active Directory from Windows 2000 to Windows 2003
Posted on 2008-11-18
I want to upgrade our active directory from Windows 2000 to Windows 2003. Now Ive done a lot of research on the best and safest way to get this done, but I felt that a final post here certainly wasnt going to hurt. With that, heres a brief breakdown of the current scenario:
Current AD mode: NATIVE mode
Exchange 2003: MIXED mode
I have two Windows 2000 Domain Controllers, Server01 and Server01 and both are running SP4. Roles are configured as follows:
SRV001: Domain Naming Master, Schema Master, Global Catalog
SRV001 is also running DHCP and DNS.
SRV002: RID Master, PDC Emulator, Infrastructure Master
SRV002: Group policies are stored on this server.
In preparation of the upgrade, I have configured two new Windows 2003 servers, both are running Standard Edition with SP2. The servers are called HO1 and HO2.
Id like to know the best route upgrade AD and to get all roles transferred to the two new servers, effectively enabling me to switch off SRV001 and SRV002.
Also, please advise if Ive omitted any required information. Thanks!
