For an upsert table I have the order columns: timeColumnName set to my updated_at timestamp. It used to be created_at when I was using an offline-only table. I believe this is the correct change. My question is for the sortedcolumn index, do I need to change it too? For my use case I generally still want to be sorting on created_at. But does upsert required the sortedcolumn be the same as the timecolumn?

No, you can keep the current sort column
