How long does the initial download take to backup your desktop version to the online version?

You're in the right place for an answer, SCIAdmin. I hope you're having a fantastic day today. 

Let me give you the maximum duration of the data migration. This allows you to manage your time and even finish your other tasks.

Migrating to QuickBooks Online takes approximately 30 minutes, but that depends on your internet speed. Be sure to keep QuickBooks Desktop running until the migration is complete to ensure it will transfer data completely. To get answers to frequently asked questions about the migration process, check out this article: Learn about converting from QuickBooks Desktop to QuickBooks Online.

After the migration, compare the Profit & Loss and Balance Sheet reports in QuickBooks Online and Desktop. From there, Check the AR and Undeposited Funds account balances individually when comparing the reports. For more details, see this link: What to do after converting from QuickBooks Desktop for Windows or Mac to QuickBooks Online.
