How do I bulk change Original Estimate?

I'm using Jira cloud. I recently created a Post Function that sets the value of Original Estimate = 0 for all new issues when they are created. Now I need to bulk change the value of existing issues from NULL to 0. 

The only estimate-related field that shows up when I select 'Edit Issues' is 'Change Time estimated (in hours)' which is an entirely different field. 

Is there some way to bulk change the Original Estimate value?

Hey @Sheri ,

Currently JIRA does not allow you to bulk edit time estimate fields. But there is a feature request you can vote for at


This can be done using the External System Import (CSV).......

Once you will try this 

Step 1: Query the issues you want to edit in Issue Navigator

Step 2: Export by CSV

Step 3: Edit Original Estimate

Step 4: Import issues



Thank you @PVS  for the help!

This solution does not work

This sugestiong is related to Server version, not Cloud.

Why would they implement something on one product and not the other?  I saw this request started in 2007.  Way to stay on top of things!  lol

Typical Atlassian timeline.... what, 15 years now!  lol

[For Server, not Cloud] For posterity, it appears this can be done starting in Jira Server starting in version 8.4, per the status update here:

Could you handle this in a transition that circles around back to itself?

Assuming all the tickets are in the same status, create a transition that drops the ticket back into its original status, with a post-function that changes the estimate during a bulk change.

If I understand your question, you can create a new transition in your workflow that transitions from any status back to itself.

Place a new screen in the transition you might call "My New Estimate Transition Screen", with a new field you might call "My New Estimate Field."

When you transition a single ticket (or bulk), the system prompts you to enter your new estimate in the "My New Estimate Field."

Using a post-function with say a 1 second delay, the system will copy the data from your "My New Estimate Field" to your original estimate field.

I am doing this in my head, and I do have JMWE loaded, but it seems like this can all be accomplished OOTB.
