Downgrading to Previous Version: Presets

I was very happy with CO20, now upgraded to CO22. Due to some CO22 issues, Hours of time spending extra every day.

I know CO doesn't support backward. I don't need latest features and don't need old Catalog at all. (Once I Process images, I delete RAW Images).

My concern is .. Presets which i developed over the period of time.

are the presets backward compatible?

Please suggest what I can do.

Thank you
