How do you find answer links when marking an answer private?

Content

Hello - 

Here is our dilemma.  We are going through our database with certain criteria and marking answers private due to inaccurate or out-of-date information or for non-use.  In doing so, one of our first steps is to search for answer in which the answer being marked private might be linked to.  We do not want our customers or agents finding broken links!  (Ex:  Answer 100 is going to be marked private.  We need to remove all links to Answer #100 from any knowledge base answers.)

What is the best way to find a list of answers that may link to Answer 100?  I have tried several reports, but not finding one that is working for us in our testing.
