How to change custom field type with ScriptRunner?

Yves Martin

 Hello

I have introduced a custom field from an add-on I no longer expect to use, but this custom field has already been added in screens and also in many ServiceDesk request types.

I would like to "switch in-place" this custom field to a standard custom field (Text single-line) so that its identifier ID remains the same to avoid to rework all screens and request types.

I expect it should be possible with Script Runner, live in JIRA without restart, as far as a re-index is triggered after operation I guess. (you understand I am not interested in known KB referring to SQL updates and JIRA restart)

May you please help to design a script to operate such a custom field type switch?

Thank you in advance

Jira itself cannot change the custom field type, so there's no API for Script Runner to call to in order to change it.I would add the new field, then

script something to read the old one into the newscript something to find where the field was used and add the new one (not replace, the API doesn't support that either)delete the old field (which will remove it from everywhere)
