I appreciate you for coming back to tread to add some clarification about your concern, Eugene Pieterse. I'll be providing extra details on how the migration method from QuickBooks Desktop to Online works. Then, to ensure you can move your data smoothly.

Since we have to temporarily hit the pause button on all QBDT to QBO migrations last June 16, yes, you can eventually move your QBDT data to QBO using the Excel CSV files.

Then, we are unable to provide a specific time frame as to when the option or tools for the migration process will be available. Rest assured that the updated migration process will allow you to move larger files with no size limitations.

On the other hand, when you migrate data from one QuickBooks to another, you'll have to ensure that you use the same International version. With this, installing and utilizing a trial version of QuickBooks for South Africa isn't currently possible. This is because we are currently discontinuing our Desktop offering in the said place.

Lastly, I'm adding this article to further guide you in effectively managing your business using QBO: Help guide for QuickBooks Online. It contains topics about different accounting strategies, banking, and payments.

Get back to me here if you have further questions about managing your QuickBooks data. I'd be more than happy to answer it for you, Eugene Pieterse. Have a nice day!
