A friend at another company of about 3,000 has recently deployed Zimbra
and is quite happy with it so far.  It uses its own IMAP/POP3 server, so
you would still have the issue of migration, but at least wouldn't suck.
Almost any of the open-source Exchange replacements should be able to
integrate with your ERP, since they're largely based on standards--IMAP,
POP, WebDAV/HTTP, etc--all of which have Java class libraries.

It's been a while since I looked at it, but OpenGroupware.org showed
promise too and it uses a separate IMAP server (in fact, Cyrus is or was
the only one officially supported).

I would assume you could use some of the imapsync tools.
