We are going to be converting to MSExchange soon, and I was wondering if anyone has had any experience with ways to get the user's IMAP inboxes and folders over to MSExchange?
Any opinions, suggestions, gotchas, or advise is greatly appreciated. No MSExchange slams please.... I know, I know.... :-)

SolutionOur goal was to replace the UNIX servers with an Exchange servers as quickly and seemlessly as possible. We wanted our users to continue using their POP clients (Eudora, Netscape, etc) without reconfiguration for as long as necessary. Only their passwords would change. Later we would migrate the clients to Outlook by department over the next year.
We spent about three months engineering the solution in a isolated test environment. Setting up the Exchange servers was easy. Creating the recipients in mass and migrating the mailboxes was a little more sticky, but not as difficult as we orginally thought. The hardest part for us was getting our user account information accurate.
We spent about a month cleaning up the scripts and procedures to maintain the accounts in the company database and UNIX servers. From that we generated CSV files defining all recipient mailboxes and lists. These files were properly formatted for import into Exchange were everything was automatically created. Also from the database we created simple lists of accounts to retire on the UNIX servers.
Now with the servers in agreement with mailboxes and addresses, it was time to push all the unread mail from the UNIX servers to the Exchange servers. After stopping the flow of incoming mail, we ran an elaborate PERL script on the UNIX servers to locate all the mailboxes for all active accounts, parse them for unread messages without the POP3 X-UIDL header, and transfer them to the Exchange servers using Net::SMTP. To expedite processing, we had the script divide the responsibility between four threads.
It was wonderful watching the internet mail connector receive and deliver the messages with a relatively tiny number bounces due to anti-virus, bogus headers, etc. For the most part it was a very successful migration.
When it was all done, the servers switched placed and all seemed well. We had a few users complain about their password being changed on them, but they were warned!
