Please double check my AD prep steps

We are currently running a 2003 R2 forest/domain function level with exchange 2010. We are looking to perform the ADprep for 2008 R2. We will not be changing the function level just yet but we want to run the ADprep to enable some of the newer features.

We are a single forest with one domain and a child domain (company.com and dmz.company.com)

Below are the steps I am planning on running.
1. adprep /forestprep on operations master
2. adprep /domainprep on infrastructure master in company.com and dmz.company.com


Questions.
1. We are not planning on running and read only DCs so I believe I can skip adprep /rodcprep
2. Im not entirely sure if I need to run adprep /domainprep /gpprep if so when should this be run?

Anything else to look out for?

All of the answers you seek are here:

http://technet.microsoft.com/en-us/library/dd464018(v=WS.10).aspx

But to summarize:

1) As the article states /rodcprep is optional.
2) /domainprep /gpprep must be run on each domain infrastructure master, just like /domainprep is. With that said, as the article states, it does not need to be run if you have already run it once for 2003. Since you are at the 2003 functional level, one could *assume* you have, but I don't like to assume.

With all of that said, there is no harm in running commands more than once. So I take the "when it doubt" path. Simply run all the required commands, and if some are unnecessary, it took a full 3 extra seconds of my time (per domain, which with 2, is a whole whopping 6 seconds.)

Hope that helps.

A few things;

 adprep /forestprep on operations master  >> You want to run forestprep on your schema master

I'd still run /rodcprep just in case you want to add them in the future

Are your current 2003 boxes 32 bit or 64 bit.  If they are 32 bit use adprep32

When you are done you will be at schema version 47   http://adisfun.blogspot.com/2013/06/windows-server-2012-r2-preview-schema.html

Thanks

Thanks guys. I was using the technet article as the guide and I guess doing all of the steps even if we arent planning on using RODC does make sense.
