Change all story points in a project [Cloud]

[Katrin Muck]

Hi!

Is it possible somehow to change all story point fields in a project?

We setup a project and already estimated a lot however judging by our recent experience we came to the conclusion that we want to multiply the existing story points by a fixed factor to be able to create smaller stories.

Another thing would be that we want to use time tracking against stories. If i change the board to use time tracking it shows that the estimate is not setup (bc its coming from a different field) - is there a way to let jira calculate this from the story point field?

Thanks
