You are moving a workflow from your staging Jira instance to production. On importing the workflow, Jira notifies you that the post-functions will not be imported.
Staging Jira is on version 6.4 and production Jira is on version 6.3.
Why did this happen?
The production and staging instances are using different versions of Jira. Specifically, staging Jira is on version 6.4 and production Jira is on version 6.3. Since there is a version mismatch between the two Jira instances, not all elements, including post-functions, are guaranteed to be compatible or properly imported. Even though custom post-functions may not always be included in workflow exports, the key issue here is the incompatibility between the two different versions of Jira, which can restrict the import functionality.
The answers I chose were C
I think it's B
I understand its not C, because XML exports some of post function, validators and conditions those are very simple but JWB doesn't actually, But why its not D any idea?
Answer is B
