I have a JIRA project that has a custom field dropdown which is multi level and has a few hundred values in it. There are people using this custom field in their JQL to add issues to their board and in their filters, so if I use this custom field in another project its possible these issues will also appear. This is a central custom field that a lot of other projects depend upon.
For this reason, I'd like to make a copy of this custom field, but how? There is no option for this. I can find solutions on taking the value of one custom field and setting it in another (with Scriptrunner), but this is not what I'm talking about. I simply want to copy a custom field instead of re-creating it and hundreds of values within it.
