how we can migrate process instances from one version to another while instance is running in camunda 8?
Suppose we have 3 user tasks created initially and deployed it.
Now I want to add user task-4 but not from the modeler may be from the code side. I should not touch the modeler. Based on any condition if I want to add another task how can I do that?
Hi @Manish_Tiwari - you are looking for process instance migrations. There are some limitations, which are explained in that link.
However, you cannot do it with an API call; you need model a new version of your process (which can be achieved using milestones in Modeler without needing a new file or losing your changes), and that process needs to be deployed as new version. Then you can migrate running instances of the previous version to the new version.
