Absolutely. I consider the migration a 2 step process anyway. I would want to see a secure, stable Active Directory deployment prior to implementing the migration for Exchange.
There are several subprojects really: 1) migrate users from NT to Windows2000 AD. 2) Synchronise Exchange 5.5 directory information with AD. 3) Install and migrate to exchange2000. The Active Directory Connector synchronises directory information between Exchange5.5's Directory Services and the Windows2000 Active Directory through the use of Connection Agreements. There is lots to be read.

We are currently using Exchange 5.5, and I would hope to move to Exchange 2000 in due course. However, I think upgrading both at the same time may be a bit too much work. Is it possible to continue running Exchange 5.5 with all the users being in AD ? Is the AD connector essential in these circumstances. I played with this scenario in a test environment, and after upgrading the domain, I was still able to access Exchange without installing the AD connector. I was under the impression that AD connector HAD to be used after upgrading. My AD domain name and NT domain names were the same, ie. DOMAINNAME became DOMAINNAME.AD. I'm a bit confused as to the role of the AD connector in this scenario. Thanks, Tony.
