I've got a long-grandfathered "free" workspace for a domain that never had Google as the registrar. I don't think there's much concern here -- Squarespace will be (unless they delegate that out) your new registrar and will likely migrate WHOIS and set up the appropriate MX/TXT/... records to keep things working. Otherwise, Google has documentation for that: https://support.google.com/a/answer/48090?hl=en https://support.google.com/a/answer/48090?hl=en
