Transfering an old Team to other

Good afternoon

I have two users on Figma. One lets call “OLD” and other “NEW”. Each one with a different mail as user.
OLD has a team with some projects and files that we used before.
NEW is our new user for the design team with a new TEAM and files.

I’ve made my user on NEW as the owner of OLD because we need to cancel the OLD plan.

My question is: when the OLD user is gone, all the files inside this team is gone too or when you transfer the owner of a team, they pass to be on the other user?
