X-5 Question

I have been using CorelDraw version 12 for years and I would like to get  X-5  but I don't  want  to download the latest version of X-5 and then have all the images I created in version 12 only open in X-5

Other then not downloading X-5 is there any other way to do this.

I understand that which ever version of  Corel is the latest version that is what normally opens all of your images.
