Thanks for reaching out, muhammadnaveed.

There are requirements you'll need to consider before converting your QBDT file to QBO. These are the following:

• Make sure QuickBooks is up-to-date.
• The company file isn't too big to export. 
  
• Some of your lists and reports won't be converted because of feature differences.

Also, converting QuickBooks Desktop (QBDT) data to QuickBooks Online (QBO) is only available for QuickBooks US, UK, and Canada versions. Since you're using QuickBooks Online International, we have different steps on how to migrate the data. 

You may also consider using a third-party application to help you migrate the data. To look for an app, here's how:

1. On your QBO account, click Apps in the left menu. 
2. Go to the Finds Apps tab.
3. In the search tab, type in the app you're looking for.

Let me know if you need more help. I'll be sure to get back to you.
