I just installed CS6 upgrade from CS5 but the Nik and Topaz software filters are not showing up. How do I get CS6 to recognize them without having to reinstall all of them again.
You will need to reinstall them. I would first check with the manufacturer to confirm they are compatible with CS6.

You don't. The behavior is as it always has been - Adobe apps never migrate legacy plug-ins and content to avoid compatibility issues. and you will probably need updated vertsions for CS6, anyway.
