If you are still using QBD 2019 or 2020 with the subscription license, you may consider 2 options
1. Purchase a new one time license for QBD 2020. If you have to comply with MTD requirements, you can use a 3rd party app. They provide a HMRC Approved web based solution for submitting your VAT returns for MTD. You can use your own excel spreadsheet or use an export Excel or CSV from any accounting program. The app costs GBP 30/year/company file + free for first year.
2. Prepare your QBO account

then contact MMB to convert your core data for the last 2 years for free. They have disabled the conversion feature from QBD UK version. If you need to convert data with specific requirements (e.g attachments, multicurrency, jobs, purchase orders, estimates), you should purchase another 3rd party conversion service due to the limitation service from MMB.
