Ignore missing migrations when reading the metadata table. (default: false)

These are migrations that were performed by an older deployment of the application that are no longer available in this version. For example: we have migrations available on the classpath with versions 1.0 and 3.0. The metadata table indicates that a migration with version 2.0 (unknown to us) has also been applied. Instead of bombing out (fail fast) with an exception, a warning is logged and Flyway continues normally. This is useful for situations where one must be able to deploy a newer version of the application even though it doesn't contain migrations included with an older one anymore. true to continue normally and log a warning, false to fail fast with an exception.
