Upgrading from version 16.1.2 to 17

I'm still on Resolve version 16.1.2 and am wondering if there is a way to make use of the new title effects in Resolve version 17 without transferring my project to version 17 yet. I have completed everything except the titles and am concerned that the settings, grades, etc. will not transfer correctly if I upgrade and render in version 17. Alternatively, would there be any issue with rendering in version 16 and then simply importing the rendered media in a new project in version 17, adding the titles (since they don't interact with the underlying media/audio), and then just rendering with titles with the imported media? My concern there is that there will be quality loss in the video/audio.
Thank you for any suggestions!
