Hi! Thanks for coming round here to ask. English is very much welcome.

I think the "most advanced" CAS we've had for the fx-9860G series is this port of Eigenmath by Nemhardy. It has reasonable support for integration (high-school level and maybe a bit more), but it's a bit fragile due to its tendency to run out of memory. Nowadays we prefer to use Bernard Parisse's KhiCAS, but it's only compatible with the much more recent G-III series due to requirements in memory and storage.

I'm assuming by fx 2.0 you mean something like the Algebra-FX 2.0 which in France is known as the Graph 100(+). This machine was a very different beast from the fx-9860G, it ran DOS and shares few technological aspects with the fx-9860G. If my understanding is right, then it seems like getting the same CAS ported over would not be an easy task. I'm not aware of previous efforts to do that, though I'm also too young to have really come across the Graph 100(+); maybe someone else will know.

are you able to transfer from the fx 2.0 plus to FA-124?
then transfer from FA-124 to the fx-9860G?

I just run eigenmath by nemhardy. It is quite ok, however the memory of fx-9860g is quite limited, so i run in some malloc problems.
