Cubase 10 Upgrade Question

Because reinstalling software is a royal PITA. I hate doing it and avoid it at all costs unless I have no choice. So if I can get 10 and keep 7 and not have to reinstall anything, I’m good to go. Otherwise, I can just keep on using 7 until I have no choice such as a VST I want doesn’t run in 7. I know it’ll happen eventually.
