QVX and QVM use the same database format SQLite, so the databases are directly interchangeable. There are several possibilities for this:
Limitations result naturally from the different functionalities.
For example, the Sketch function does not (yet) exist in QVX, so sketches assigned to a waypoint in QVM cannot (yet) be displayed in QVX. However, they will not be lost.
Conversely, links from QVX cannot be processed in QVM, because the function does not exist in QVM. Therefore no linked files are transferred. However, the links are not lost, they are just not evaluated.
We looked at the App Syncios. They are available for free for Mac and for Windows.
This allows you to copy QVM databases to the QVM_Data/DBs folder in an iOS device connected via USB cable.
Note: the App Syncios is not from QuoVadis Software Gmbh. It is a product of a Chinese software company. Therefore use it at your own risk and peril. We mention it here anyway, because in our experience it does a good job and fills a real gap.
