Server 2012 R2 IPv6 DHCP high availability

I have configured failover for my IPv4 DHCP, and would like to know what to do about IPv6.
If I enable IPv6 one of the DHCP servers I can set up reservations and DNS servers and all that good stuff, but if that server goes down then there is a big mess.

What is the recommended solution?

Autoconfiguration is not an option.
And router advertisement is so scary I don't want to go that way either.

I just hate it when a wireless access point or worse still a laptop changes the default gateway.
Don't have the  resources for an IPAM.

How do I keep reservations in sync on split scope servers?

The failover for IPv4 is so easy and pretty robust.

You can't keep reservations in sync automatically. That'll be a manual process. 2012 comes with an IPAM as a free installable role.

I could not get the IPAM to work for IPv6. Have you tried it?

It works with DHCPv6 and DNS. It does not work with stateless autoconfiguration, which you stated you didn't want to use. Yes, I have tried it.
