      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.

      When using MigrationManager api in a Kie-Spring application, the following stacktrace is seen:

      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.
