Find and edit links in OneNote 2016?

How can I search for all links in my OneNote 2016 and then edit them with find and replace? I expect more than 200 links in a big OneNote notebook, which will need editing their linked address (link to network folders and pages in OneNote notebooks), due to major changes in our company folder structures. I didn't find any search function for this, and would not know, how to search and replace parts of the linked address.
