mixing and matching

I have what I suppose to be a first gen 1.4x TC that I use with my 600mm f4 lens.

I am thinking of buying the 7D2 and the current 100-400 is II as well.    Would the old TC work with that,

or would the new electronics require the newest gen 1.4?

It is hard to have to replace everything!  (I am sure many of you have gone through this).

A quick followup.   If I sold *both* my 1st gen 1.4 and 2.0 TC, is there any issue with using the 1.4 gen 3 with my new 7D2 and the old 600 f4?

Although the old TCs may not be worth much, anything to help offset the cost of the new gear would help...

The most recent releases are supposed to always be backwards compatible.

I don't have one but I would say no problems at all.
