No, I don't think it would be necessary to do that. What I would do is take one of the laptops or desktop and uninstall the AC program and install 8.2.2 (temporarily).
Then install 8.2.2 (obviously without SQL) on another computer. Like one of the laptops. See how well that works. Just be sure to put a big sign on the computers with 8.2.2 on them so others don't use them by mistake. While I have imported all of the data using the AC backup -- which helps with all of the other settings, I tend to stick with just loading one patient. This way, if someone uses it accidentally, they will notice right away.
I doubt you will leave it set up that way anyway. If you do, you can also change the name of the AmazingCharts.xml file to AmazingCharts.xyz, and the other computer wouldn't be able to access that database.
I would test, test, test. If you put 8.2.2 temporarily on a computer with an SSD and you put 8.2.2 on a client on an SSD and it is very fast, you may want to install one on a computer without an HDD just to see if there is a difference.
Obviously, this is something you want to do at night or the weekend.
