I'd basically first audit the entire infrastructure. Doing this will tell you about other problems (if any), so that you can take proper decisions.

Second I'd also talk to my customers - ie the developers on the challenges, pain points they are facing.

Next - you'd have two options. One is to build something (semi-automated or fully automated) or write scripts to achieve those tasks. Or you can consider buying an Internal Developer Platform. There are a lot of solutions out there that can solve for your potential needs. The answer depends on whether you have the internal expertise and bandwidth to do something like this. If not, buying an IDP would be a better idea.
