We're very aware of the need for a migration plan.  To that end, we're
maintaining a migration guide as we do new development:
  http://design.ros2.org/articles/migration_guide_from_ros1.html
Here's a complete example of how to migrate a very simple package:
  http://design.ros2.org/articles/migration_guide_from_ros1.html#example-converting-an-existing-ros-1-package-to-use-ros-2

It's likely that those changes could be largely automated, at least
for simple cases.  We haven't tried to write those scripts yet, so we
can't yet say how far we can push automated migration.
