We are currently using JIRA agile, and want to modify the JIRA agile workflow. JIRA agile workflow cannot be modified because upgrades will wipe out any modifications you perform to the workflow. This is also written in the description of the work flow.
Generated by JIRA Agile version 6.3.0.2. This workflow is managed internally by JIRA Agile. Do not manually modify this workflow.
The documentation does not provide an alternative to modifying workflows. I want to modify the workflow such that setting to "Cannot Reproduce" changes the resolution to a resolution that I want. This can be accomplished with a post transition function... if I was able to modify the JIRA AGILE workflow.
