How recovery value in customfield in issues jira ?

[Alex]

Hi,  Atlassian comunity!

I would really appreciate some help on this issue.

Task.
After incorrect automation, the data was lost in the field. The values ​​were saved in the ticket history, and they were even able to be downloaded from the database. Can I somehow add them back? (values ​​disappeared in approximately 400 tasks)

Any help is important! Thank you!

Hi @Alex 

Yes definitively you can try to import back values. If you have values already downloaded from the issue history that is a good start. Now you can try to import them using for example CSV 

https://support.atlassian.com/jira-cloud-administration/docs/import-data-from-a-csv-file/

If you look at the above documentation there is a section of "Updating existing issues"

Another option is to create a simple script that with help of REST API would update affected tickets. 

No matter which solution it would require some preparation and would be good to test it on a test system first.
