So a manual update/copy of the settings will get you close on control deflections and such. The rest of it won't be much use as the newer Spektrum stuff is so much different to program than JR.
That said, the programming is much more intuitive and if you just let the radio guide you through the initial setup, when you get to setting control deflections there will not be a lot to change. I would NOT leave the servos connected to their surfaces while you do this and mixes/flight modes will not transfer either.
As a matter of practice, I ALWAYS start out with less expensive models on a new radio, usually my foamies.... lol
The DX20 is a nice radio and I think you will enjoy it, but it is just a bit different to program than your JR.....
If you measure the servo pulse width at mid point and max throw in both directions on the old Tx, you can use them to set the new Tx exactly the same and there will be no difference when you fly the plane. A buddy suggested this when I switched radio brands, it's brilliant. No need to even re-trim the plane.
