talking email here, not other functionality, you can write a script to transfer mails from server a to server b. most scripting languages have hooks to imap, so you write a script to connnect to exchange server via imap, read each mail for each user, and transfer it to that user's account on server b (running any imap server). Not trivial, not impossible. see discussion here: http://www.oreilly.com/catalog/mimap/chapter/index.html the other solution would be a real drag for a situation with a lot of users, but I have done it here for two or three users when migrating from uw iamp to cyrus on different servers. get a client that allows more than one imap account. set up old_account (pointing to imap mail on exchange server) and new_account (to imap account on new open source server). Sit at client computer and drag and drop folder contents from one server to the other. tedious but effective. amazing how much redundant stuff you delete :-). you have to manually create the new folders (although there is discussion on a possibly better way in the oreilly link above). creates a lot of network traffic :-( > > We have made a partial change - I run squirrelmail on the webserver > (linux) which is a webmail/imap gateway, and that runs fairly well. > > Users will loose all the calendaring/schedualling/addressbook components > of exchange server too, when you change to something else. if the situation is clients on outlook/windows and server on !(exchange server) then you can get outlook connector, it costs, but that may be less than the exchange server licence. This solution will allow you to store outlook style conacts and calendars on any imap server with acl support.
