[IMail Forum] Migrate from SmarterMail to Imail

[Vincent Toussaint]

Anyone know if there's an "easy" way to migrate SmarterMail to Imail?
I run SM on a corporate network (around 100 users, 25 mailing lists, 25
aliases).  Most users run IMAP. if they were all using POP, I wouldn't
have any problem shutting down the server for a couple hours to switch
the software. But since 60% use IMAP, I need to find a way to move their
messages to the Imail installation.
 
Any input will be welcome!
 
P.S Our CEO wants the new Imail to be up and running before the end of
the week.
