1. Take the backup of your existing WFA2.2. If you are planning to install WFA3.1P2 on a different windows box( other than where the original wfa2.2 was present) , then you need to take the wfa key from the existing wfa. How to take this key? See installation and setup Guide. its simple 1 line CLI step
2. Install WFA3.1P2 freshly.
3. Restore the backup obtained in step(1). Restore the key as well if it was required.
No need for any intermediate WFA installations.
