Emails missing after VM GPL --> VM Pro Migration

Restoring a VMGPL backup into VMPro emails are missing from VMPro.

User inboxes on GPL (/home/mail/) are not captured in the backup at all even with "All features" selected in the backup form. I can tell they have not been captured based off the size of the archive.

Their IMAP folders are captured, but not imported to the Maildir, instead they just sit in the user's home dir.

There was a similar problem with the IMAP folders here:

I note there was a script discussed in that thread called convert-users.sh. May I please have a copy of that? That will solve the IMAP folders problem, although it would be nice if VM Pro could just take care of this.

As to the inbox emails not being captured I am at a loss as to what I should do. For the one and only domain I have transferred I just used Fetchmail, but this is not a sustainable solution for the scores of other user accounts.
