Safe to uninstall RW 7?

Upgraded to RW 8 a couple of months ago. Works great. Wondering if uninstall of version 7 - with all its stuff tucked away in nooks and crannies - could have any negative impact.

BTW, I do keep a backup of everything, so it would not be devastating, but I’d like to get rid of the old version, if it can be done cleanly and without impacting version 8.

Thanks for your thoughts.
