If you had an Overflow beta Cloud account, we suggest you sign in to the new Overflow with those credentials. This will ensure that your Documents get transferred.
Once you’ve created or joined an Organization, please contact us at email@example.com and ask for a transfer from your personal account to the Organization’s account.
Essentially you will be transferring folders with Documents from one organization to another. Please send us the details of your current account/organization and the organization you want to copy to and we will take care of it.
