Regarding 1.)Yes, the importer expects an existing OPNsense on the disk to be imported or at least one that is emulated using a /conf/config.xml file. The importer actually also grabs your backups and other things it knows about...Regarding 2.)With respect to 1.) we support reading from UFS and ZFS per native OPNsense installs or emulated using FAT.Cheers,Franco
