GR (amongst other things) is a generalisation of Newton's law of universal gravitation, Newton's laws can be accurately derived from both QM and from GR with the PPN framework being the most common tool which derives it's parameters from the predictions set by GR.

Newtonian gravity works perfectly well in weak fields so it is not "wrong" but rather it's just not a generalised theory. A good way to look at it is that the laws govern the flow rate in a pipe are not a good generalisation of the behaviour of fluids in motion but they are as sure as hell good for calculating how liquid will flow in a pipe.

And wile GR tied everything together the signs that Newtonian laws were not a generalised theory predate Einstein in fact the Lorenz Transformation which serves as the basis for GR pretty much proved that as if the speed of light must taken as a constant and be finite which as defined by Newtonian physics then we get variable length and time.

So no GR to Newton isn't the same as Heliocentrism to Geocentrism if anything is that Geocentrism didn't actually work even with the math and observation we had.

The Greeks understood the Helicentric model quite well and even considered stars as distant suns the only problems with their models were primarily due to measurement errors for example Aristarchus's measurements were wrong by a few degrees but that was enough to alter the distance and size ratio of the moon and the sun to being about 20 times which what the greek calculated from being about 400 times which is what we've eventually measured correctly when we had better tools.
