Unfortunately that kind of technology doesn't exist yet. Not only would we need the means to transport large amounts of people into space safely, but we would need to make ships that could travel MUCH further and find planets that could sustain life or develop the technology to make uninhabitable planets livable. I'm guessing it will be close to a century before we can really even take the prospect seriously.
