It will make rewrite quicker, not "easier".

When the management recognize a tech debt, often it is too late that nobody understand the full requirement or know how things are supposed to work.

The AI agent will just make the same mistake human would make -- writing some half ass code that almost work but missing all sorts of edge case.

I was involved in a big re-write years ago. The boss finally put the old product on his desk with a sign "[boss's name]'s product owner" - that is when people asked how should this work the most common answer was exactly like the old version. 10 years latter the rewrite is a success, but it cost over a billion dollars. I have long suspected that billion dollars could have been better spend by just fixing technical debt.
