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

If you have a small amount of tickets, then you can use automation, create a Scheduled automation and use JQL to find issues with empty original estimate (originalEstimate is EMPTY) and edit issue fields in the automation. 
Once you create the automation, press on Run rule button and waiting until the automation result becomes Success.

[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.
