Camera RAW update policy for CS6 is here: Update to camera support policy in CS6
Note that you can allow CS6 to render if the camera is supported by Adobe Camera Raw (v 9.1.1), otherwise pass a TIF/PSD or convert to DNG.
Hi Adrian Wood.
Use the link below to update your Lightroom - http://blogs.adobe.com/lightroomjournal/2015/11/lightroom-cc-2015-3-6-3-now-available.html
Note - LR 6 uses camera raw 9.3 however PS CS 6 has camera raw 9.1.1, https://helpx.adobe.com/x-productkb/multi/camera-raw-plug-in-installer.html
So if you are using raw files from a camera that is supported by camera raw 9.2 or higher then you need to switch to Photoshop CC
