Possible to get rid of without rebuilding everything?

Hi all,

Back to years ago, the consultant set up our forest
with empty root domain and one child domain. Right
now, the forest functional level is windows 2003.
and all DCs are windows 2003 domain controller. All users
and servers are on the child domain.

Currently, we are thinking to move to Windows 2008
DCs. If we need to get rid of the empty root domain.
is this possible without affecting our applications
(exchange etc..)? BTW, why is the reason to keep this
empty root domain?

Thank you!

You are stuck with the root domain forever. Root domain is no longer
considered a best practice, the fewer domains the better.

Build a whole new Forest/Domain with the 2008

Do a normal Domain Migration.

Use the Active Directory Migration Tool (ADMT) for the Domain.

Use Exmerge combined with the Swing Server method for Exchange.

The Docs and Guide for both products will tell you all you need to know to
use them. The are several KB Docs for using the Swing Server Method for
Exchange.

The Domain Migration can be spead over time, but I don't recommend
stretching it out too rediculasly long.

Exchange with Exmerge needs to be done start to finish in once shot after
the mailbox contents are copied accross with Exmerge. But you can take you
time with it up to the point just before you use Exmerge because until then
the "swing server exchange" is not really being used for anything yet.

In the end, the quicker you complete the whole entire process after begining
it the better off you are,...so don't drag it out any longer than you are
forced to do.

Thank you for your help.

That's what I thought and that's the design that the consultant did for us
years agao.

If we need to get rid of the empty root, domain, that means we need to
rebuild everything (servers and users etc...), right?

I would agree with Phillip and start over with a new domain and migrate, if
you have the time and resources.

The other option is to colapse the child into the root domain.
Occasionaly an intraforest migration can be better than an interforest.

How well do you like the root domain namespace?

Thanks for your help.

If I build the new domain, migrate the users to the new domain. What about
our exchange servers? that means that I need to build the new exchange
servers in the new domain. I can not use the movebox since it's in the
seperate forest, right? What about all others app servers? I have to
re-join the domain? Also, all workstations need to rejoin the domain? We
have some apps that needed to extend the schema too. That means these
application we need to reinstall also.
Definitely, we have downtime.

I would rather just keep empty root domain, ask your insights on this.

thank you.

That depends on the version of Exchange currently running, and going to. Can
you describe the Exchange installation in more detail, such as version, how
many, if installed on a DC, and which version you want to go to?

You can also opt to use the Exmerge tool 2-step method. Step 1, export to
PST, and Step 2, import from the PSTs. This assumed ADMT was used to migrate
the users first into the new forest. It uses the Exchange Alias to match the
PST names. Public FOlders are migrated using PST method. You can spend some
money on third party tools too, such as from Quest, to make it easier.

As for AD, I agree with the others it will be beneficial to start from
scratch.

Hello ed,

Without a complete migration with ADMT you cannot get rid of the empty root
domain, so you have to keep it or migrate. I prefer the latter. Are there
any other applications then Exchange and which version is used, also from
Exchange?

Best regards
