Let's ensure you can seamlessly migrate from QuickBooks Desktop (QBDT) to QuickBooks Online (QBO). John.
In QBDT, we have the Condense Data utility, which removes old, closed transactions and their audit trails to reduce file size and improve performance. However, please note that this feature is currently only available in the US versions of QuickBooks Desktop. The UK version does not include this option, which is why you're unable to find it under the Utilities menu.
Since you're using the UK version, the only way to reduce your audit trail file size is to delete the old transactions manually. Alternatively, you can consider creating a new company file. You can export important data such as customers, vendors, and charts of accounts from your existing file and import them into the new file. This will reduce the file size and make it easier to migrate to QBO.
Additionally, you can refer to this article to learn how features and data move from QBDT to QBO: Find out how your books will move from QuickBooks Desktop to QuickBooks Online.
Please return to this thread if you have other questions about managing your data in QBDT, John. We're here to help you every step of the way.
