Mine are all setup to auto renew. The news ones get installed right before the other ones expire; and, it is (in my case) all hands off. Originally, they use to be that way, which was a hassle when you had to do it manually. I like the aspect of having a new cert a couple of times a year, in the aspect that the security is updated without the (off chance) risk of the cert getting hacked and reused somehow and somewhere else. They are grabbing quite the market share over the past few years.
