import VirtualBox vm into Parallels 15: Hard drive is not recognize

I have a virtualbox vm in .vbox format that I am trying to import into Parallels 15 without success.
Parallels starts to import the .vbox file but then I get an error message saying " the virtual machine does not have a Hard Drive do you want to continue?"
In fact the virtual machine I need to import has 2 Disk (*.vdi) mounted on the SATA controller.
Any suggestions would be appreciated.
