I'm here to assist you in migrating your QuickBooks Desktop (QBDT) company file to QuickBooks Online (QBO), @Snafix.

Firstly, I appreciate your efforts in troubleshooting the issue and reaching out to our support team for assistance.

To provide an accurate solution, could you please let me know which version of QuickBooks (QB) you're using?

To address your Profile 2 Problem 1, I recommend following the advice of the support agent and creating a new ProAdvisor account with a different email address. This will prevent QB from overwriting your data.

Regarding your Profile 2 Problem 2, you can use an online tool to move your books from QBDT to QBO since you can't access the migration button. Let me guide you how.

1. Choose the link for your QB version:
   • QuickBooks Pro/Premier
   • QuickBooks Enterprise
   • QuickBooks for Mac
     • Convert your QuickBooks for Mac file to QuickBooks for Windows before you use the tool.
2. Select Get Started and log in with your Intuit Account.
3. Click Select File and look for the supported QBDT file you want to move. It's important to note that you can only upload one file at a time.
4. Select the Open button or drag and drop the file to upload it.
5. Once your file is uploaded, we'll automatically update it to the recent version of QBDT. Then, you'll see an option to move to QBO.
6. Follow the on-screen steps to move your data to QBO.

If you still encounter any issues while migrating from QBDT to QBO, you can contact our support team for assistance. They have the right tools and resources to take a closer look at your account and provide a solution.
