Greenhopper upgrade from 6.0.x to 6.1.1 created duplicated custom fields and broke scrum boards

[Alexey Paveliev]

For some reason update thru UPM created duplicate fields for Story points and Sprint custom fields.

Any ideas why and how to fix this?

I was able to copy values from old fields to new ones using Groovy Script Runner canned script.

Then removed old fields. It appears to work fine now
