Hello there, @carolee8.
I understand your sentiments about migrating QuickBooks Desktop to the Online version.
I'm here to share a few details about the converting limitation from QuickBooks Desktop to QuickBooks Online.
Some information may not transfer due to import limitations and feature differences between QuickBooks Desktop and QuickBooks Online.
You can only import QuickBooks Desktop data within the first 60 days of your QuickBooks Online company start date. When you import, your Desktop file will replace your Online file and overwrite any existing information.
I suggest you keep your data file in QuickBooks Desktop and maintain your transactions on both sets of books until you determine QuickBooks Online is right for your business.
To learn more about the limitations, please check out this article: What data doesn't convert from QuickBooks Desktop to QuickBooks Online?
I added this link for the common question about converting your account from QuickBooks Desktop to QuickBooks Online.
In addition, If you receive any errors while importing, you can fix errors when converting to QuickBooks Online.
If there's anything else you need help with, please reach out to me. I'd be sure to jump in as soon as I can. Thanks for posting, and have a great day.
