Some questions:

When you copied all the .seen files, did you dump to flat format and then
recreate in the new db format?

Did you migrate the mailboxes.db before or after reconstructing the
mailboxes?

What do the .sub files contain? On my (very small) system, I found just
a list of mail folder names.

thanks and regards,
