[Koha] DATA MIGRATION REQUEST

Dear colleagues, I have checked for previous questions on migrating data from INMAGIC to KOHA on the KOHA users forum as we have just installed KOHA at the World Agroforestry Centre Library and are hoping to migrate data from INMAGIC version 9.0 to KOHA. Unfortunately I didn't get a useful answer. Could someone please help. We intend to migrate data from INMAGIC version 9.0 which is not MARC-based, to KOHA. Any help, will be highly be appreciated.
