Ask your accountant, which QB Desktop country version she/he has. If she/he is using QBD UK version, you can only migrate it to QB Online UK version. You may restore the QBM file on the trial license of QBD UK version and migrate it to QBO UK version.

But if you are using QBO South Africa version, you may have 2 options:

1. Install the trial license of QBD UK and restore the QBM file to open it. Utilize a 3rd party tool to migrate the data. i.e TPExporter for Desktop, TPImporter for Online
