Hi is there a way to downgrade my vxdiag vcx se version to 1.6 and back to new version without loosing my license or hardware?
No, it is not possible once you update you can’t go back.
VX Manager FW1.8+ has a different license. You will lose all licenses after downgrading.
You can downgrade with loosing licenses.
After return back to the FW1.8+ licenses restored from the VXdiag server.
Newly installed licenses completely overwrite old.
Actually licenses for the VXDiag SE FW1.6 should be the same as VXDiag nano.
Better don’t downgrade firmware.
