There is a standalone Lightroom 6 you can upgrade to.
Go to Products, scroll down to Lightroom 6, click on Buy, change "Full" to "Upgrade".
What do you mean "Lightroom 5 doesn't recognise my cameras when I upload?"
thank you so much that is really helpful! And I am relieved! Don't want to go the cloud route! It's ok I have sorted my camera recognition!! Many thanks
