cloudHQ can be used to migrate all or just selected Dropbox accounts to Google Drive.

Single user migration:

If you are looking to migrate just one Dropbox account (either personal or Dropbox business account), then you just need to create a migration sync pair from indivdual Dropbox account to Google Drive account or to Google Drive Team Drive. The main limitations of that approach are that sharing metadata is not migrated.

Multiple user migration:

If you are an admin of Dropbox for Business domain and G Suite then cloudHQ can:

  1. migrate all your Dropbox accounts to corresponding Google Apps / G Suite accounts. All sharing metadata will be migrated too.
  2. migrate all Dropbox Team folders to corresponding Google Team Drives.
