Active Directory Migration

What is the safest/Cleanest way of migrating from NT4 to Active Directory on a 2003 Machine? (The NT4 machine is not capable of being upgraded) I have seen software out there and I am wondering if there are any that would be effective. I do like the fact that you can reverse it if there are issues.

I think did it upto some extent 3-4 years back….for this purpose had to create .tab files(on C++) from prev OS…and had to import on new OS…was a large project
Hope it works

    the easiest and safest way, would be to purchase a server that is hardware capable of running sever 2003 sp2, install nt4 server and make it bdc. then promote it to a pdc. then you can upgrade that server to server 2003 AD. if you can get your boss to purchase two new servers. you should create your forest root with those new servers before upgrading your existing nt4 domain. install all your esential services, like dhcp, dns etc in the forest root. then upgrade your existing NT4 domain and join it to the forest root as a child domain. This way you have all your esential services up and running before you make the migration or conversion. it will make the upgrade smoother.

    Buy a new server that will support you future needs. I have done many NT to 2000/2003 migrations. Basically, you take a old workstation that has enough power to run 2000/2003 AND has NT drivers. The biggest thing is the NIC drivers. I keep an old 3Com just for this purpose. Build this temp server as NT with SP6, join it to your domain, make it your primary DC which will demote your current one. Then do an in-place upgrade on this temp server to 2000/2003. While doing this you can also build your REAL 2003 server. Don't worry about activating this temp server as it will only live for a few hours. This is a link that explains it better and the one that I initially used. best of luck dmw

    Here is the process we used to migrate from NT4 to 2k AD a couple of years ago. It may provide you some useful information or some things you might need to think about. When we migrated we also changed our internal domain name. HTH, Gary
