Exchange Question

Currently have two domains, but am converting to a single domain. Domain A is running Exchange 5.5 with about 30 clients. Domain B (will be the single domain) is running Exchange 2000 in a test environment. I am looking for advice for the easiestmethod of getting the 5.5 accounts over to the 2000 box. Again, these are separate domains…no subdomains, trusts.

I am guessing that I will have to 1) Create domain and e-mail accounts on 2000 server for the 30 DOmain A Users 2) Copy all 5.5client mail to PST’s then 3) Import PST’s to Exch 2000 server.

If the two servers were in same domain/site…then I could simply move mailbox locations I believe, but our setup is tricky.

Any advice appreciated. Thank you!
