If you have an existing free account, you can choose to use the same email address to join a Business team. All of your docs will move with you to your Business team.
You can also choose to create a new account with a different email address. In that case, you’ll start with a brand-new, empty account.
Note: If you were using the old release of Dropbox Paper and you joined a Dropbox Business team using the new 2020 release of Paper, the docs from your old account can only be accessed through the search bar on dropbox.com. You can use the search bar to find your Paper docs by their titles or the content within them.
If you delete a team or cancel your Business subscription:
Note for admins: If you’re an admin, all content you own will move back with you to your personal account, including shared docs that you’ve accessed before or have been invited to.
If someone is removed from or leaves a team, any “private” content (docs they’ve created that haven’t been shared with anyone else) will migrate back with them to their personal account.
Any shared docs that were created by that member will move to the admin’s account that removed the member.
