Motion of the spherical shell at metric junctions among the Minkowski, Schwarzschild and de Sitter metrics is investigated both for a dust shell and a vacuum energy shell. Using the positive energy condition for the shell, some junctions are excluded. Different junction leads to different self-energy or different expansion rate of the shell.
