We have an embedded system in one of product offerings that was largely developed using a bunch of “antiquated” technologies (over the past twenty years) and over the past year the two software devs that maintained it have retired. This normally would have big problem, but the entire codebase was re-written, documented, and modernized in a matter of about 3 months (for about $20k in tokens, and a mid level developer spending 50% of their time on it over that period). So it doesn’t surprise me to think a company like Cisco has piles of situations like this.
Curious, why did it take 3 months and not a few days? Honest question, just curious about what is consuming all the time in a project like this?

That's really interesting.
What have been achieved using this port?
And how did you make sure the port is correct?
Every time something like this has been done on my company I follow up with the question: did anyone watched the code to see if the business logic is the same between the two versions?
The answer is: but but but automated testing.
Followup question: did anyone read the automated test suite?
Silence.
The software rewrite is shelved.
