I read on line that if you have 2003(32bit) DC's, you must run adprep from the 2008(32bit) ISO.  I have done this, but noticed that the schema version is 44 (2008RTM).  I am ready to put some 2008R2 DC's in place.  Can I do this as I am now (/forestPrep & /domainprep /gpprep), or are other steps needed to get the schema to 47 before 2008R2 DCs can come on line?  I have a single AD domain/forest running at 2003 functional level, 7 sites.

ADPREP 2008 vs 2008R2

I read on line that if you have 2003(32bit) DC&#39;s, you must run adprep from the 2008(32bit) ISO.  I have done this, but noticed that the schema version is 44 (2008RTM).  I am ready to put some 2008R2 DC&#39;s in place.  Can I do this as I am now (/forestPrep &amp; /domainprep /gpprep), or are other steps needed to get the schema to 47 before 2008R2 DCs can come on line?  I have a single AD domain/forest running at 2003 functional level, 7 sites.
