Migration of AD 2000 to 2003

Hi,

This is the first time I'm doing this so just want to be sure.

I need to migrate AD 2000 with Exchange to AD 2003 without Exchange, as we are using Lotus Notes now. I presume that prior to the migration, I'll need to do some housekeeping first to remove all the Exchange Groups that are still residing in AD 2000. Also, I read about the ADMT 3.0 which can automate and simplify matters for me on the migration. Not to forget DNS and DHCP servers configuration.

Are there any steps that I should take note of or missed out?
Kindly advise, thanks.

Save a lot of pain and upgrade your existing domain to AD 2003 rather that migrating to a new domain.

If you're using Windows 2003 R2, you'll need to do your ADPREP from the second CD.

ok lets start with the easy parts, DNS and DHCP are not a big deal, you can easily lower the lease time to few hours right before you migrate, or minimize the pool size , once you migrated have the DHCP back to its old, every1 should try to get their ips from it normally.

DNS will build itself automatically, i dt think its crucial to export DNS entries (one less mess)...clean start is always great when suitable

Concerning the AD 2k to AD2k3 , you should get the forestprep tool in Microsoft to prepare your active directory to be able to talk the lagnuage of win2k3, add a DC (win2k3) to your domain ,then just migrate the global catalog to the new PDC.

moving from Exchange to Domino, i beleive your tool would be useful, not much experience there...

always have a lab if possible (VMWARE OR SMTHN)

Cheers

bad times moving to Lotus Notes, bad times, i hate that mail system with a passion :)

You dont need to remove any exchange groups....you will just wreak havoc with AD if you try....

Are you doing this all on the same box?

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Lotus Notes have already been migrated out about 3 years back but the old Exchange stuff are still residing in the current AD 2000 server. The new AD 2003 server will be another newer box.
