Just downloaded OS 10.9.2

Now that I upgraded to OS 10.9.2 I have duplicates of some of my programs. I have the original pages, numbers, and keynote, and now a new version of each.

How do I delete the old versions? And if I do, will it mess up the new ones?

Also, if anyone has used this version, can you tell me any bugs you've found and anything that's really different from the previous version that may help me out?

Thanks!

If you have any work done on the older iWork suite you may want to keep it awhile.

Good advice. The older iWork suite will be placed in a separate folder by itself. The new iWork apps have just recently been updated and will show up separately in your Applications folder. Keep both.
