Does the proprietary solution allow IMAP access? If so, I would use imapsync.
Thanks for answers.
Not all the accounts have IMAP enabled, but I guess I could setup some master account with IMAP enabled or even enable IMAP for all users to proceed with migration. But will imapsync keep trac of UIDs so users won't have have duplicated messages or re-download them if they use POP3?
I don't think so. The sync happens via IMAP, and I don't think IMAP clients can *set* UIDs of messages; only the server does this (someone please correct me if I'm mistaken.)
Will it preserve flags of messages so read or deleted messages do not appear as new messages? Yes; at least, it has for us in testing (with Dovecot as the destination server.) Whether it will work for you depends on the specifics of the source server. Why not give it a try and see?
