Your DNS will continue to work as long as there is at least one valid root server address in the hints file.
This is true as long as the old IP address is taken out of service, i.e. doesn't answer "." DNS queries at all or - as in this case - continues to serve the "right" NS RRSet. And, the ftp copy is not necessary, because "dig @${X}.root-servers.net. . ns" does the job (for $X in A .. M) - unless you trust the DNS less than you trust ftp - after the "root-servers.net" zone will have been updated. -Peter
