java.lang.Object
- org.dspace.storage.rdbms.xmlworkflow.V5_0_2014_11_04__Enable_XMLWorkflow_Migration

All Implemented Interfaces:

org.flywaydb.core.api.migration.jdbc.JdbcMigration, org.flywaydb.core.api.migration.MigrationChecksumProvider
```
public class V5_0_2014_11_04__Enable_XMLWorkflow_Migration
extends Object
implements org.flywaydb.core.api.migration.jdbc.JdbcMigration, org.flywaydb.core.api.migration.MigrationChecksumProvider
```
This class automatically migrates your DSpace Database to use the XML-based Configurable Workflow system whenever it is enabled. (i.e. workflow.framework=xmlworkflow in workflow.cfg)
Because XML-based Configurable Workflow existed prior to our migration, this class first checks for the existence of the "cwf_workflowitem" table before running any migrations.
This class represents a Flyway DB Java Migration http://flywaydb.org/documentation/migration/java.html
It can upgrade a 5.0 version of DSpace to use the XMLWorkflow.
