Find and replace a string in a JQL filter

[Sigursteinn Bjarni Hubertsson]

Hi.

I'm having similar issues as https://community.atlassian.com/t5/Jira-questions/JQL-filtres-find-and-replace/qaq-p/621341.

I need to swap out the name of a one project role for another in a JQL query. This role is currently in 132 filters. I'm not very keen on doing this in the database and I was wandering if this is a problem I could solve with script runner.

I'm a script runner novice, so if anyone could point me in the right direction, that would be great!
