Brikit Targeted Search 2.0+ makes it easy to swap one label for another.

Use the "Replace Any Label" tool in the Folksonomy interface to swap one label with another. Doing so replaces the old label with the new label on all the pages, blogs, and attachments of which you have edit permissions.

Check if you have Targeted Search 2.0+ installed

This "Replace any label" tool is only available in Targeted Search versions 2.0 and greater. 

Navigate to the Folksonomy Page

Via Confluence Administration menu:

Scroll to the "Replace Any Label" section

If you have a large number of folksonomy labels, you may need to scroll to the bottom of the page to see this section.

Enter in your values

For the "Old label" field, type in the currently-used label that you want to replace. For the "New label" field, type in the new label value. You can also type in an existing label. These fields must not be blank. New label values must not contain spaces or special characters other than underscores.

Click Replace

The old label will be replaced with the new label on every page, blog, and attachment to which you have Edit permission access.
