Convert Virtual Buddy VM to UTM

I created a MacOS Tahoe VM in Virtual Buddy on an M2 MacBook Pro. For better functionality, I would like to move it to UTM. Google finds how to move UTM to VB, but not the other way. I tried extracting the .img file and using it as the drive, but it generates an error message that the VM may be corrupt. Does anyone know if htere is a way to convert the VB machine to UTM? If so, please provide the method.
