exchange server

We have recently moved our server to win2k server from NT4.0
Our domain name is our company_site
What we would like to do is move some folders named public folders from Exchange server on the old NT server to our new 2000 server.
We have tried using exmerge but get error messages when tryin to intsall exmerge itself. Is there any way we can get these folders and their content from one system to another?

Any help much appreciated
