https://us.community.samsung.com/t5/Galaxy-S23/Calendar-from-S10E-to-S23/m-p/2536877#M5799 In my experience, you have to ensure that all of the calendar events are saved to Google or Samsung account to ensure they transfer over. Only way I've found to ensure that is to edit each event individually. I'm not sure if there's a way, now, to select multiple and save to either account.
