I SEE K&T that has been in use for 80+ years in better shape than NM in use for 20 yrs.

Most damage is at the devices. Where exposed to all that deadly O2.
(That Mr. Gore wants to out law) (OOPS)
However,I do recommend it to be -Upgraded- Not changed- Unless serious issues are found.

Most issues 'Needs' can be addressed with a service upgrade or new ckts to an already upgraded service.

Most N&T I see,is in better shape than the added stuff.
