Use virtual machine manager again to create a Q35 VM and re-use your disk image. Note that this is the same as moving your disk from one machine to another with potentially different disk and network controllers. If you're using virtio for both, you're probably fine otherwise you might need to go back to the 440fx machine type and install extra drivers to make it work. Also be sure to maintain the same firmware type in the VM, SeaBIOS or OVMF. Switching between the two for an existing VM image is non-trivial.
