Replacing custom fields with drafts
If you copied an active custom field to create a draft field, you can replace the existing field with the draft when you finish configuring it.
Note: You may not be able to replace an active field depending on the properties. If an error is displayed, you need to delete the existing active field and then promote the draft to active to make the changes available. See Promoting draft custom fields.
