So as the title asks. I was thinking and it makes sense to me that it happened but couldn't find anything that proves it.
I was thinking how east had thriving economy, but was that thanks to westerners moving to east or just east by itself.
I don't know what more I can say on my part since I am no real historian but I need to have here some more text so that bot moder allowes my post to go through.

Some probably did.
But for the most part, I don't think it was the case.
The process of the Fall of the western part was in fact quite long and not to be seen as one big wave of soldiers invading and killing everything. If it had been the case, then probably more roman migration would have occured indeed. But actually, the "barbarians" were already in the Roman landscape since quite some time. Quite a number of them was holding high positions within the military and it is even said that, by the end of the western part, most of the armies was barbarian or coming from barbarian bloodlines. All of this while the last emperors were losing in power and prestige.
Also, the Fall of the empire was probably not perceived the same way according to where you were living in the Empire. A citizen of the City was probably more concerned of losing the Emperor than let's say a farmer in the countryside who only knew approximately the emperor's face thanks to the money coins.
We must also not forget quite an interesting fact. The "barbarians" had no interest in destroying the Roman culture and infrastructures of supply and power. It appears that they actually wanted to preserve and pursue it (just have a look at how some leaders even yeeeears after the Fall did their best to bring the Empire, or at least the idea of the Empire, back). Some of the new people in charge actually asked for councelling from romans of long roman bloodlines on how to keep everything in place.
This probably helped in having the smoothest change as possible and so to not "scare" the roman people.
I would add that even 100-200 years after the fall, people who were descending from old roman families were much respected and had quite some positions of power, still as councellors or within the Church, which worked closely with the new powers in place across West Europe to maintain society.
