How to change assignee (in subtasks) all in one, some subtasks in different tasks

[Leena Laine]

I mean some subtasks in different tasks

If you can find all the concerned issues with some criteria, you can do a bulk change and use operation Edit.

Then change assignee field

Hi Leena, you could do a JQL search like 

project = OPS2 AND issuetype = Subtask

And then use the bulk change tool

Note the use of the bulk change has to be granted by an admin.

I used: 

project=<project> and type=Sub-task and parent=<parent's key>

From there, bulk update as noted above.

Do you mean all subtask of one task ? Or all subtask of the project ?

It was a question not an answser !
