We use payflow pro which is at the bottom of the third table. How can I verify that we are up to date before the two hour test occurs?

Answer 1

The 2 hour period will basically test it for you

There are several resources linked in the document you reference, most notably this. However, you need to be sure you have 1. Discontinued use of the VeriSign G2 Root Certificate, and 2. Updated your integration to support certificates using the SHA-256 algorithm.

The document I linked should guide you down the correct path.
