2000 to 2008 Migration question

Hello,

We are in the process of upgrading our windows 2000 (32 bit) domain to
windows 2008 R2 (64 bit). We are ready for the process but I have few
questions regarding running "prep".

Our domain consists of 10 domains. One Parent and 9 child domains and each
domain has 2 windows 2000 DC's. I am starting the upgrade with the parent
domain.

On the Parent domain I am to run processes before introducing win 2008 r2
DC:

adprep32 /forestprep (schema master only)
adprep32 /domainprep
adprep32 /domainprep /gpprep
adprep32 /rodcprep (infrastructure master only)

Should I run any of the processes above against the second DC?

Also, When it's time to upgrade child domains I must run:

adprep32 /domainprep
adprep32 /domainprep /gpprep

Both against the PDC. Should any of these be run against the the second DC?

Thank you in advance.

Hello Raul,

/forestprep on the schema master, no need to run it on the second DC also

/domainprep /gpprep in each domain with Windows server 2000 DCs. /gpprep
to enable RSOP planning mode

/rodcprep once in the forest, the IM is contacted automatically and replicates
to all other IM in the forest

Before starting the upgrade run support tools dcdiag /v, netdiag and repadmin
/showreps to check for errors. Therefore install the support\tools\suptools.msi
from the 2000 installation disk.

Keep in mind that you have to give time for replication of all changes throughout
all domains before doing the next steps, this belongs to your AD sites and
services replication schedule and also the bandwith between the sites in
the forest .

Hello Rahul,

Apart from what Meinolf said, am sure you know that a 32-bit OS cannot be
upgraded to a 64-bit OS. You will need to introduce new servers with W2k8 R2
OS as DCs.
