So if I understand you correctly now, you have you have two volumes to which you store mail. I'm not really sure how to move mail between the volumes. But I have a theory or logic.
When mail volumes are created they would have the same file or directory structure, so in theory you may be able just move the mail on the disk. May also require re-indexing or editing the database.
Thats just my theory, don't trust it too much. If you do attempt then I seriously suggest making a backup. But your probably better of not doing it at all. |
