It's just a matter of accounting for the stars true space velocities and their vectors of travel. Simple 4D mathematics.

I agree this is not a problem, scientist already know where most of the star a going and you you never travel far that it would take a 100 years to get there.
We need to manage the environment on Earth 1 first before trying to live on an artificial environment for longer than we have technologically live on this planet.
