@jasonhuck am I reading this right, we can keep our free G Suite Legacy account? Are there any downsides to keeping it? I don't see any, but maybe I'm missing something. We do get to keep using our personal domains. support.google.com/a/answer/…

I just got the notification, opted out on the domain I hadn't migrated yet, no issues. Now I have to decide whether to migrate the other domain back or leave it where it is (Zoho Mail). I don't mind it except you have to use their client, & the spam filter isn't as good.
