Minor problem when migrating from a linux server to another

i got a new server with a new host it comes with cpanel just like the old server.

i migrated all data from the old server to the new server except one e-mail account which was transfered to the new server but without the created folder and e-mail messages.

i created a new folder at the old server called needed but that folder along with e-mails messages never got transfered

how can i transfer it manually?
