Is there any way to test v3 models (like Apollo) in v2

I tried to copy .json and in v2 locations with different combinations with no luck. But may be somebody managed v.2.6.4 to see this model?

There is hear-say that 1.9.0 can run all the new models and old ones. No one’s tried Apollo on it, and I finally saw the results of the old Artemis models and was less than impressed. So I never bothered to install it and try it myself.
Basically, I might be wrong about all of this.

v.2.6.4 does not have .Json files
