Ops engineer who built half our automation just gave notice. Nobody understands the system

Ok so our operations engineer just gave his notice a few days ago, and I just realized how much of our mid-size startup relies on what he built over the years. He wrote tons of automations that move data between systems, generate reports, trigger approval, and all the other QOL stuff. I mean everything still technically works and we had a good chat. (He got a better offer and I completely understand his decision, we still keep in touch from time to time, especially when I have questions.) But the thing is, nobody unedrstands how things work except him. There are some resources that he left behind, although they're pretty outdated, so now upper managemetn it scrambling asking if we can still keep things running. For those of you who have dealt with this, how do you recover when everythging is basically locked inside the automation stack of an employee who just left?
