So this is the issue - my client will migrate to QB's online on 1st April 2022 BUT they still need access to the Desktop version for historic data.

As QB's desktop is a subscription product how do they use it to access their historic data (mainly attachments that are not migrated) from 1st Feb 2023 (as I assume the subscription service will cease)?

We really need this clearing up as this matter has dragged on for too long.

The community need a clear formal statement from QBs as your support team do not have an answer.
