Cbase Pro 10. Do I need to uninstall an older version of Cubase Pro 9 when upgrading to Pro 10?

Hi. Sorry, I’m new to this forum. I have Cubase Pro 9. I want to install Cubase Pro 9.5, but the official site offers an update only to Cubase Pro 10. If I buy Pro 10, will I be able to download and install 9.5 somewhere?
And more. When installing a new version, do I need to uninstall the old one? How is this even done – an update?
Forgive my ignorance)
