Hello there, @JC5970.
You can upgrade your QuickBooks Desktop (QBDT) Pro 2021 to 2024 instantly without installing other versions. To start, make sure that you already purchased your QBDT Pro 2024. It would also be better to have your license number handy as this is necessary for this procedure.
Next, refer to these steps in upgrading your version:
1. Start with downloading the QuickBooks Desktop Manager.
2. Next, click Download.
3. Select the QuickBooks License Agreement and click Let's get started.
4. From there, enter the license number to look for your QBDT 2024 and select Search.
5. Then, pick the email address you use to receive OTP. Once received, enter it in the dedicated field.
6. After that look for your QBDT 2024 and select Install.
7. When done, select Open QuickBooks and activate it.

Once everything is fine, your next step is to update your company file so you can now use it using your QBDT Pro 2024 version.
I'll be right here in the Community if you have any other queries about upgrading your QuickBooks versions. I'd be glad to provide answers to help. Have a good day ahead.
