Hi there, @kaissi79. I'm happy to share more information about updating your QuickBooks Desktop version to 2024.
When updating your version from 2022 to 2024 in QBDT, I recommend updating them all together as they are not backward compatible with 2022. If you update your computers one by one, the 2022 version will be unable to access the company file. I also encourage reading this article know more about company file compatibility: Company file compatibility with QuickBooks Desktop. The tips listed in the article will help you avoid issues and errors when you upgrading the program.
Yes, we need to update the QuickBooks Data Server Manager so that all computers can open the company file later. Also, the 2022 version still belongs to the system requirement by QBDT. I assure you that you can still use the 2022 version.
Additionally, you can check out this article to learn and guide you on upgrading your account: Upgrade QuickBooks Desktop Pro Plus, Premier Plus, or Enterprise.
