public class ProcessDefinitionVersionMigration extends Object implements MigrationTask
This migration is used to extend the data we have on process definition versions. We used to keep track of only a single version. This version was the highest known version of the process definition.

For resource deletion we need to know all the versions that are available in the state. This migration will make sure we store a list of all known versions.
