10.9 Installed, recovery is 10.8.4

Question

Hello. I am running 10.9 Mavericks, but my recovery partition shows 10.8.4. How can I upgrade it to 10.9? Is it possible without a disk wipe? What is the procedure?
Thanks all.

Thanks for your insight JimHess.  Someone else on another post pointed out how Photoshop changes the color profile and other things and then trying to make this file into a DNG again confuses Mavericks (and, presumably, other flavors of OS X).  Admittedly, the process I described is unorthodox and not what may want to do.  Thank you.
A.J.: First, I am offended by your suggestion to omit my comment.  I was simply trying to provide help in finding a cause of a general problem people are having across the internet.  That problem, as you pointed out, is that modifying a DNG in some way in photoshop results in the thumbnail no longer being visible.  Your modification is the size.  Mine was not.  But it was a general modification in photoshop and an attempt to reconstitute the file as a DNG that seems to be common theme, whether this workflow makes sense or not.  Additionally, I'm very new to digital photography and tried to be helpful.  I would advise you (as an educator who knows the consequences of negative first-time experiences) to be more mindful that not everyone on here is as experienced as you and everyone can benefit from being clearer in their questions and their comments.
Second, as JimHess pointed out, in manipulating a DNG file in any of the programs in a way that alters the actual file (not changing some setting that is ultimately stored in a side-car file or does not actually alter the photo) is probably the root of the problem.  Changing the file size by altering pixel count may first require one of your adobe products to physically alter the file information in a way that stops Mavericks from being able to recognize the contents as RAW information.  Does this make sense?
