I have communicated with QBO and QBDT for the past couple months to get ready for the migration. On Monday, I was going to do the QBO data export for the migration and following the steps in this article (Export and convert your QuickBooks Online data to ... (intuit.com)), but the URL at step 2 (to export view) stops working. Then, I have contacted several OBO CSR, and they told me they have stopped providing the data export for QBO to QBDT migration since last December. Is this true? 

Then why both QBO and QBDT instructed me to follow the steps in the article to do the migration in Feb 2021, and also spent so much time to communicate with me about my concerns about the self-migration in the past couple months and even last Friday? It is wasting both our time for nothing! It is very disappointing!
