Migrating from 2003 to 2008

Our domain is a part of a larger forest controller by our "home office", and
I use that term loosely. I see the documentation for upgrading from 2003 to
2008 that forestprep, adprep, etc have to be run before upgrading.

Do we have to upgrade the Forest controllers first? or can upgrade ours to a
2008 domain without having the entire forest convert as well?

Hello BillyTWorthington,

You have to upgrade the schema master to the new schema version 44 from the
2008 installation disk with adprep command's, this FSMO role exist once in
the forest. Does NOT mean to upgrade the OS to 2008.

After the schema upgrade you can install 2008 DC's in the domains.

So the step would be to run to run adprep.exe /forestprep on my Home Office
Schema Master and then to run adprep.exe /domainprep and adprep.exe
/domainprep /gpprep on the DC in my domain that is the Infrastructure Master.
Then I can upgrade my DCs to 2008. Would it be better to upgrade or install
new ones?

Hello BillyTWorthington,

/gprep is not needed when 2003 is running, only when you upgrade 2000, but
doesn't matter if you run it.

I prefer fresh installed machines ,but you can also do an inplace upgrade,
if the hardware and software on the machine is compatible with 2008.
