How import to on-premise backup to web Ragic

Hello anyobody.
Today i tried to import one backup file of my on-premise installation to the web version of Ragic.
But i was told my backup was db4 and wen Ragic needs db7.
Is there any way to make on-premise installation work with db7?
My installation is running on a QNAP-NAS.


Please select Compressed backup in order to restore it to the account in different db version.
