So, some mistakes were made, and one of our 2 front-end servers in our SP2013 farm was reverted (VM snapshot deleted) to a state that is about 2 years old.
Now I'm wondering what might need to be done (and if it can be done without any weird side effects in the farm) to get it operational again.
I believe in the time since the machine was last online, we have updated SP2013 to service pack 1, changed the SSL certificate, and some upgrades to Symantec endpoint protection running on the server.
Now, because we're load balancing with a 3rd party product I can easily keep the new server out of the load balancing config so that no clients will ever be accessing the server, but is there anything else I need to be concerned about with bringing a server that has effectively been turned off for 2 years, back online in the farm?
Should it be as simple (haha) as turning the server back on, applying the SP1 update and updating the SSL cert?
