When I migrated 1Password (version 3.8.22) to my new MacBook Air, I was told that my free trial expired and to subscribe. I did that and I now have a 1Password Account on 1Password.com. How do I migrate my old vault (kept in a Dropbox folder) to my new account. I'm concerned about installing the new app on my MacBook and blowing away the existing vault.
1Password Version: 3.8.22
Extension Version: Not Provided
OS Version: OS X 10.14.3
Sync Type: Dropbox
