Hello Diane18,
It's awesome to hear that you're getting a new computer for your business. You've got a great question here about how it will work with moving your QuickBooks Desktop and your company files from one computer to the other. I can help you with this and let you know more about that feature you use to switch between companies.
Each QuickBooks Desktop company file is its own entity, meaning they'll have to be moved over one by one. You can do this by putting the company files onto an external or USB drive and then take them from that drive and put them on the new computer.
What you're seeing with being able to switch between companies happens when you've opened the company files in the program. It's the program's way of recognizing the data that has run through it and allowing you to easily go from one to the other when necessary. Once you've opened all the company files in QuickBooks Desktop on the new computer, you'll be able to switch between them in this way again.
If you'd like a hand during any part of this process, don't be afraid to reach out to support for assistance. Learn how to do that by reading our Intuit QuickBooks Desktop software support policies article.
We've got your back!
