Many so called "professionals" are still running operations with 5+ year old distributions that haven't been patched in almost as many years, and servers that people are afraid to reboot. I was once contracted by a company that was literally afraid to have any employees reboot a server because they had no idea how it worked, if it would come back up, and what to do if something didn't restart. They wanted an outside guy to take the blame.
Would’ve been a decent opportunity to contract a job paid half up front.
I took the job on the side. It was literally the equivalent of "set up a couple of static web servers with FTP accounts, and move everything over." It was about 8 hours of work and 100 hours of meetings.
