      1. Create a Kie-Spring based application like: https://github.com/mswiderski/spring-jbpm-app
      2. Add a /migration endpoint with a controller like:

      @Controller
@RequestMapping("/migration")
public class MigrationController {
    @Autowired
    private DeploymentService deploymentService;

    @Autowired
    private ProcessService processService;

    @Autowired
    private UserTaskService userTaskService;

    @RequestMapping(value = "/", method = RequestMethod.GET)
    @ResponseBody
    public String performMigration() {
        try {
            KModuleDeploymentUnit migrationSource = new KModuleDeploymentUnit(
                    "example",
                    "migration-target",
                    "1.0");
            migrationSource.setStrategy(RuntimeStrategy.PER_PROCESS_INSTANCE);

            KModuleDeploymentUnit migrationTarget = new KModuleDeploymentUnit(
                    "example",
                    "migration-target",
                    "2.0");
            migrationTarget.setStrategy(RuntimeStrategy.PER_PROCESS_INSTANCE);

            if (!deploymentService.isDeployed(migrationSource.getIdentifier())) {
                deploymentService.deploy(migrationSource);
            }

            if (!deploymentService.isDeployed(migrationTarget.getIdentifier())) {
                deploymentService.deploy(migrationTarget);
            }

            ProcessInstanceMigrationServiceImpl processInstanceMigrationServiceImpl = new ProcessInstanceMigrationServiceImpl();

            processInstanceMigrationServiceImpl.migrate(migrationSource.getIdentifier(), 3L, migrationTarget.getIdentifier(), "migration-target.migration-process");

        } catch (Throwable e) {
            e.printStackTrace();
        }

        return "Success";
    }
}

      3. Attempt to perform a migration.

      This appears to be due to a ClassCastException in TransactionManagerFactory.get().newTransactionManager(env), from Spring's JtaTransactionManager to javax.transaction.TransactionManager. Other components of the KIE services wrap the Spring txm when initializing (SingleSessionCommandService and TaskTransactionInterceptor), but MigrationManager does not.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
