I should move some vertices of a polygon to fix the boundaries of a country, how can I do it while keeping the adjacent polygons still connected? Is there a way to anchor permanently overlapped vertices of adjacent polygons?

I'm using Qgis

In Settings -> Snapping Options,

Check the box that says Enable Topoloogical Editing

Now you can move the shared vertices together.
