I am trying to upgrade from my (very) old desktop versions of 1Password to the new subscription-based functionality. I attempted to follow the instructions at https://support.1password.com/migrate-1password-account/, however, it appears my version of 1Password is so old that these instructions do not apply. Specifically, it says to click on the "Accounts" icon on the Preferences window, but my Preferences does not have any such Accounts information (see attached screenshot).
Please let me know how I can migrate my years of passwords from my prior versions (I have it on Mac, Windows, and iPhone) to use the new subscription-based approach. I just bought a new Windows laptop and don't know how I can get my 1Password data on it since there is no longer a desktop version.
1Password Version: 3.8.20
Extension Version: 18.104.22.168
OS Version: OS X 10.11.5
Sync Type: Dropbox
