I work in defense contracting and version control is either non existent or dated at most companies. I've gotten very good at selling git to management.

2 months to introduce those kind of changes usually mean it will still be in the "people don't want to change their way of doing things" phase. With most of the infrastructure half deployed, the process ready to be cargo-culted and a lot of things directly copied from stack-overflow into critical parts of this process. The know-how never got shared and won't appear to fill the void.

That our hypothetical tornado managed to start introducing change during just 6 months is imho a strong sign that at least some people want to change. In my experience introducing changes takes years.
