To be clear:

 - there is no configuration change necessary in the next 3 weeks for resolvers
 - there is no configuration change necessary in the next 6 months for resolvers
 - even after 6 months, chances are resolvers which are not reconfigured will continue to work as normal

These changes have happened before (other root servers have renumbered). I have never heard of an operational problem caused by such an exercise, and I guarantee there are resolvers running happily today with hints files that are *ancient*.
