How get the latest process definition of camunda irrespective of a process instance

I'm trying to get the latest process definition to perform various operations irrespective of any specific process. I also wanted to migrate my existing processes to the latest definition. Can someone guide me for the same? Docs are not of much help.

Solution

  • You can query deployed process definitions using the RepositoryService (assuming you are using the java api):

    repositoryService.createProcessDefinitionQuery()
    .latestVersion()
    .processDefinitionKey("myProcess")
    .singleResult();

    For process instance migration, you can create and execute MigrationPlans:

    MigrationPlan migrationPlan = processEngine.getRuntimeService()
   .createMigrationPlan("exampleProcess:1", "exampleProcess:2")
   .mapActivities("assessCreditWorthiness", "assessCreditWorthiness")
   .mapActivities("validateAddress", "validatePostalAddress")
   .mapActivities("archiveApplication", "archiveApplication")
   .build();

    as documented here. There is also a community extension for instance migration , which is a bit outdated, but at least should give you some ideas how to work with the API.
