Can you transfer a QB account to a Techsoup QB account?

@JanbonN I'm a bit confused about your response "A direct transfer of your QBO account to TechSoup QBO account is not possible. However, I suggest exploring a migrating tool to assist with the transfer."

Our non-profit recently received the TechSoup QBO Plus subscription, and in the activation email, it states:

Step One: Activate Your Subscription

1. Go to the account setup page by clicking the activation link below.  (Link removed)
2. If you already have a QuickBooks Online subscription and want to copy your company to your new subscription, click the link to sign in to your existing account. Otherwise, fill in the form to create a new account.

However, when I click on the link, login, and select the organization, I receive the following error: (screen shot below)

(I couldn't upload the photo b/c I don't know what is wrong with your system)

The error says: 

You can't add QuickBooks Online Plus to Upturn Arts with your existing subscription. Try another company or contact customer support for help.

Finally, the email message states that if you create a new company, you'll need to copy info from the old subscription to the new one, but only if the original subscription is QBO Advanced!

Copy a Company from an Existing Subscription

To copy your company from an existing QuickBooks Online subscription to your new donated subscription under the same account, follow these instructions after you've completed the above steps.

Please note that copying a company from an existing subscription is only available if your original subscription level is QuickBooks Online Advanced. Otherwise, you'll need to upgrade your subscription before you follow these instructions.

1. Sign in to your QuickBooks Online account.
2. Switch to your old company that has a QuickBooks Online Advanced subscription.
3. Follow Intuit's instructions beginning at Step 2 to enable backups and copy the old company data to the new company you created when setting up your donated subscription.
4. Cancel the QuickBooks Online Advanced subscription for your old company.

Needless to say, this is all very convoluted and confusing.  Can you provide any clarity on the path I need to take to move our current QBO Plus paid subscription to the TechSoup QBO Plus subscription?

Thanks in advance for your suggestions.
