[Vikrant Yadav]

Hi Guys,

Need help

I want to update the Fix version/s automatically when someone update the Fix Version/s in the linked issue.  For eg :- I have Issue A which is having Fix Version/s :- 2.1.2 and Issue B which is linked with Issue A with issue link type "is covered by". In Issue B Fix Version updates to 2.1.3 then system automatically update fix version in Issue A. Please suggest how can i do this. 

I have script runner plugin installed.  Do i need to use REST API or Listener or Trigger..what would be the best solution.
