Testing a Backup Insteon Hub (2245-222)

I am running HA on a Windows 10 laptop running Oracle VM VirtualBox. All of my Insteon equipment is running well using my existing hub (2245-222). As recommended by others, I purchased another 2245-222 hub as a backup (plugged it in and the LED is red). Is there a way to test the second hub using my HA that is currently installed to see if it can actually communicate? I read here that you cannot have two hubs running simultaneously. However, I was wondering if there is a way to install both in HA but disable one while testing the other. Unfortunately I am not a sophisticated user so I am looking for any possible testing methods that may be geared for a newbie! Thanks for any ideas.
