Hi Daniel2022,
It's a pleasure to see you in Community. Welcome! I'm happy to hear that you're remaining with the QuickBooks family. QuickBooks Online is a great way to complete your daily bookkeeping tasks while on-the-go, with access through a web browser or the QuickBooks Online mobile app. I'd be happy to provide more information so you can get back to business as soon as possible!
Due to the vast amount of files in QuickBooks Enterprise, the best course of action for a smooth transition to QuickBooks Online, would be through our Data Services team. I recommend contacting us outside of Community, so we can gather the necessary information and start the migration process in a timely fashion. Here's a helpful guide for moving your data to QuickBooks Online.
Feel free to reach back out if you have any other questions or concerns. We're here for you!
