they are still running everything on UNIX. They simply cannot upgrade because they have a 100% up-time requirement.Are you saying that they are running on 40 year old hardware and software that has NEVER been down for maintainence or upgrades?

For the most part, yes but maybe closer to 20 years. These are newer UNIX machines and they can get software upgrades.
Swapping out the entire system for an entire infrastructure upgrade? Not happening.

If they’re running vmWare they simply move whatever Unix app they have to another server while it’s running. The users never notice it.
