Let's walk through what happens when I want to create another version of the Subject1 page because I update thetechnology that's used for it. Continuing the example above, I will want the page ABC123_Subject1 to redirect to ABC123_Subject1_Technology3 instead of ABC123_Subject1_Technology2 # Create the new page [[ABC123_Subject1_Technology3]] and populate it with content.# Go to the redirect page you created, [[ABC123_Subject1]]. This will redirect you to another page but it will say (Redirected from ABC123 Subject1) at the top, which you can click on.# Edit the redirect page and make it redirect to the new page [[ABC123_Subject1_Technology3]] instead of the old [[ABC123_Subject1_Technology1]] Note that the redirect page will keep a history of all the edits, so if you click on history you can find a list of all the versions of that subject page that you've ever had.
