Hello all, I have a question about how the HA licensing works. I have quite a few old SonicWalls TZ215's and they are/were setup as HA way back when they were initially installed. I was not the one who set them up, I've taken over for a company and have inherited all of this. When I look at the licensing for their products it doesn't show any active HA licensing. So my question is, how is this still working if the licensing is not valid? I have tested failover and it still functions. Is HA licensing a one-time purchase or must it be renewed every year? Perhaps it's only required to setup/configure for the first time?
