Updating my anking deck without losing the card easing and agenda

I was using the ankingv10 deck, I want to update to this new anking deck, but I don’t want to lose the agenda of cards that have not been modified. Also, I made a lot of new sketchy decks and I’m afraid of losing these decks that I made, in the sense of downloading this new deck will change the types of notes and tags present in my anki decks? Is it possible?

It won’t affect your scheduling or any cards you’ve personally made!
