    55We've tried to make this process as unobtrusive as possible.  However, there were a couple of unforseen hiccups.  This page outlines the hiccups we encountered.  It also explains what to do if you were affected.

     9Dovecot's documentation [http://wiki2.dovecot.org/Migration/Courier warns] about scenarios where this might happen.  A pop/imap server keeps some information about what messages you've downloaded, and what messages you haven't.  Part of the transition involves converting this information from `courier format' to 'dovecot format'.  We incorporated this conversion step into the upgrade.  However, during one upgrade (chavez), we made the mistake of allowing dovecot to start before the conversion was complete.  This allowed some members to check email before their mailboxes had been converted; and their mail clients downloaded all messages from the server.

     11To prevent this from happening again, we modified the upgrade process so that dovecot and courier are stopped while the conversion takes place.
