2000 to 2003 AD Upgrade
Posted on 2006-05-02
We have a native multi site W2K AD environment. Our hub site has two W2K DC's which are running on aging hardware. We've purchased two new servers and have Windows 2003 Server running on them. We would like to upgrade our AD to Windows 2003 by adding these two new servers as 2k3 CD's and decommisioning the existing 2 DC's. What process would I follow? Don't I run adprep first on the schema master? One of the two existing DC's is holding all 5 FSMO roles and we would like to transfer them to the 2 new DC's (so we can seperate the Infrastructur Master from the GC server). At what point can we raise the domain functional level to Windows 2003? After the OS has been upgraded to 2003 on all our remote site W2K DC's?
If anyone who has been in this situation can shed some light, I'd appreciate it. I also heard that you should disable outbound replication on the DC that is becoming the first W2K3 box in case something goes wrong?
