That is a great question. I have to be perfectly honest with you I like 
Microsoft products overall and I like Exchange, but Exchange 5.5 to Exchange 
2000 or 2003 migrations are just not fun and a lot of work off hours if your in 
a large environment.  If you do not do these type of migrations daily, I would 
really consider using a firm that specializes in these type of migrations. 
Quest, Allin, Microsoft Professional Services, CCO computing and others all 
have specialists that focus on this daily. They will provide you the best path 
for your migration and understand how to deal with any issue's that might arise 
( Such as Blackberry Enterprise Server and Cisco AVVID for the Call Manger 
System  ) integration issue's.

If you decide to do this your self take a look at:

We are under NT4 domains (4 trusted domains) and need to migrate to AD
Our Exchange 55 in NT4 domain is slow in performance and Direction is
pushing heavily for the new OWA of 2003 and all its features.

We plan to create a 2003 AD parallel to our NT4 domains and our first
priority will be to migrate Exchange 55 to Exchange 2003 in the new 2003
AD. We will then gradually move other servers to new AD domain.

What would be the recommended steps in achieving a successful exchange
