HOW TO CREATE A LINK: Select the text or image > From the image settings or text settings menu select Link > browse to insert an element from you files or to create an anchor link choose "Another Area on this Page > Click the down arrow to reveal the anchor link choice. Click Anchor link > You'll see the Anchor Element. Place this element in the desired position on your page. As far as using an existing link, you'll need to fish through your link file.
You WILL have to re-anchor those things. I don't think you will have to option to rename them the same as the old links, so you will actually be making NEW links. The originals MAY be hiding behind a photo or image. You can try to move them around on the page in editing mode to see if you can relocate them.
