Match up two polygon layers in QGIS

Geographic Information Systems Asked on November 1, 2021

I have two polygon layers, one is from natural earth data (Administrative 1 division) and the other is a polygon layer with some historical regions in Europe. As you can see in the image attached there are some areas which still has the same boundary, but since these two layers come from different sources they don’t match up, is there a way I can match this automatically in QGIS 3.10?

I tried the snap geometries to layer tool and it just didn’t work. (either it caused QGIS to crash, or the output was just the same as the input).

You can also use the Move Feature(s) tool to move your polygons. Select the polygons you want to move, than activate the tool and move the selected polygons with the mouse. If you enabled snapping, you can snap the moved polygons to the other ones so that they overlap perfectly.

If not visible, active Advanced Digitizing Toolbar in Menu View / Toolbar.
