Merging 2003 and 2008 ADs

Long story short:

Had an AD of 4 2003 servers.  Started adding some 2008 R2 boxes to the mix.  It is my understanding that the 2008 boxes were running in "AD 2003 Mode".  

Now that I have three 2008 boxes up, how do I "elevate" them to 2008 and shut off the 2003 boxes?  I have already moved shares, DNS, DHCP, all that good stuff to the 2008 servers.  I am leaving one of the 2003 boxes online as a print server.

Thanks.

This article from Microsoft should explain everything you need to know.  I assume that new 2008 boxes are already domain controllers running the 2003 schema.  If not you would need to dcpromo them first and then upgrade the schema.

I have already done the ADPREP.  I was thinking more along the lines of FSMO roles and all that stuff.  Once I shut off the 2003 servers, am I all set?

have you seized the fsmo roles onto one of the 2008 boxes? Need to do that first.

Well both 2008 servers are already members of the AD.  They are just running in 2003 mode.

So I need to seize FSMO roles, THEN update them to 2008 Mode?  Or are there more steps?

Thanks.

Once the roles are seized then you can remove the W2K3 DC's only then can you upgrade the forest functional level.

OK, since both boxes are still online, I think I can transfer the roles as opposed to seizing.  Thanks.
