Um, I don't have such a document. The migration path I took was:
 * I had NFS over IPv4 for a long time. I used hostnames only in fstab and
   /etc/exports, as there was no problem with search order. 
 * I enabled IPv6 on both client and server, setup DNS to have foo.domain
   point to the v4 address (A record), and foo.ipv6.domain to the IPv6
   address (AAAA record). I also had a "search ipv6.domain domain" in
   /etc/resolv.conf of both machines. 

   I'm now aware that this makes resolving of hostnames in fstab and
   exports (etc. :-) dependent on information in /etc/resolv.conf, which
   may not be wanted as an extra thing that needs changing. I've then
   changed both files to contain FQDNs (foo.domain, for IPv4) to make
   things clear and not be dependent on resolv.conf.

 * To switch to NFS over IPv6 then, I changed the server's /etc/exports
   and client's /etc/fstab to use foo.ipv6.domain, restarted the necessary
   processes, and that's it. It just works. :-)
