Will An Existing (Non-Semantic Mastery) GSite And Drive Stack Interfere With The Ones Being Built By MGYB?

In episode 258 of our weekly Hump Day Hangouts, one viewer asked if an existing (non-Semantic Mastery) GSite and drive stack interfere with the ones being built by MGYB.
The exact question was:
hi guys i was talking to a dentist about his seo. he told me his son was doing it but was getting nowhere. I spoke to the son and he told me he bought some gigs on fiver for google sites and drive files. i told the dentist you get what you pay for and that I may be able to help do it properly. Can I go to MGYB and buy a gsite+drive stack for this or is it too late? will the current gsites or “”drive stack”” his son setup interfere with one mgyb would build? I dont think the son will let me delete all the work he had done. thanks
