About to upgrade to DaVR studio -advice needed!

I've just upgraded - currently downloading, and have the license key. Will the new installation overwrite the free version, when I install? I'd hate to lose my projects - I assume they're compatible - do I need to protect them anyhow, before installing studio?

TIA

How can I upgrade from DaVinci Resolve to DaVinci Resolve Studio?
Once you have your activation license or USB dongle, make a backup of all your current Resolve projects and files.

Download the latest version of DaVinci Resolve Studio from our website and follow the instructions in the manual to uninstall the free version of Resolve, and install the Resolve Studio software.

We highly recommend you back up your project database and export any active projects. Details to do this are in the manual. All your projects and files should automatically be brought over from anything you were working on in the free version but a back up is a prudent step before upgrading.
