suppose I made some change to the current python type of digital assets, how to save a new copy of the updated DA?

It seems that, on the “edit operator type properties” panel, if I save the DA to a new library with a new name, it will remind me the following:

operator saved to “…DA_new.otl”
but the current definition is in “…DA_old.otl”
…

Thanks!

advices are greatly appreciated!

What about if you delete old one from “Operator Type Manager” !?
