How to distinguish the SafeGraph and Advan Patterns datasets?

Dear Dewey team,

Your documents mention the differences in data processing methods between the legacy SafeGraph data and the newer Advan data. I am currently downloading Advan data from the Dewey API. How to distinguish the SafeGraph data from the Advan data? E.g., Monthly Patterns before 2024.01.01 is SafeGraph data, and after that is Advan?

Thanks,

Huan
