No, you cannot just purchase an extra upgrade.
You can move the 9.2 license only if you're able to deactivate it at the latest system where such license was installed. Software and license needs to be running.
If you're getting a "no deactivation mode" notice, then such machine is NOT the latest system where such license was activated, and therefore it cannot be transferred.
With CMS IntelliCAD 12.1 PE PLUS licenses we provide users the option to convert a digital license in to a USB Flash drive serving as physical license to run our software.
In such case, you can install our software at any number of PC systems and run the software where the USB Dongle is installed.
That's provided for free to users running the latest version of CMS IntelliCAD PE PLUS software.
If you need to move the license, then just move the USB Dongle.
No activation or deactivation is required in this case.
