Abstract
A method and apparatus is disclosed for moving a unit of data (such as an object, program, or file) from a computer operating at a current release level N to a computer operating at a previous release level N-M in a manner that assures that the unit of data will function predictably when restored to the previous release without having to make modifications or updates to the N-M level computer system. This invention allows a new release to be gradually phased in for a distributed computing system instead of requiring that all computers be upgraded to the new release before any units of data can be moved between systems.
