Migrating Mail from Plesk 8.3

I have a customer on Plesk 8 with about 30 email accounts. Is there an easy way to migrate the accounts to Interworx? I know there’s a 7.5 import function but 8 has been around for quite some time.

I really just need mail, I can copy everything else.

I believe the importer also works on 8. Not sure if it’s been tested on 8.3 yet though. If you have any problems importing your account, open a support ticket and someone can take a look.
