Transfer eC mail from old computer to new computer

Have been using eM client for a couple years now.(600+ E-Mails). Bought a new computer. How do I transfer E-Mails from old to new computer in eM client?

By creating a backup: Menu -> Settings -> Backup. Be sure to restore the backup to the same eM Client version on the new computer.

Another workaround is to copy the files in de Storage (Menu -> Settings -> Storage) location from the old computer to the storage location on the new computer.
