Once you've got your DMVPN up and running, as shown in DMVPN, you can enable IPv6 and OSPFv3.
Note that the config is largely the same as the IPv4 version. The critical difference is the references to the link-local addresses (FE80::). Without these defined, OSPF will have issues maintaining adjacencies. I've also kept the global addresses mentioned (2001:DB8:DDDD::), mostly for things like pinging and SSH.

Spoke Configuration
Again, the configuration is largely the same. As with the IPv4 version, the NHRP redirect option has been removed.
