Detailed Description

Stack migration definitions

The migration definitions are used to defined the specific functions
used for migrating stacks between specific versions.

The `MIGRATIONS` dictionary contains the mappings between
`'%(from)s-%(to)s'` version strings and the specific function to
perform the migration.  The specific migration functions should be
denoted as private to this module.
