The answer to this was supposed to be sending perferred lifetime=0
broadcasts from the router out on down networks, forcing the devices over
to one of the remaining networks that are active for new connections.
The issue of only operating on one of the two or more networks is not an
issue, as long as the traffic is distributed close to equal among the
available active networks which can be done by simply splitting your
bandwidth over more than one provider.
However most current IPv6 stacks will not shut down the broken route, and
herein is the problem. If that problem could be solved, multihome for the
masses would be much much easier, without any expansion of the v6 routing
table like is required to use the BGP solution. This is the problem that
I wish the IETF would help us solve.

Broken from this step onwards. You now have two default routes and two
IPv6 addresses with access attempts from external users to both. Many
of your devices are not smart enough to match the route to the source
address. Others are capable (e.g. Linux) but only if you're savvy
enough to do some custom configuration beyond an entry in the /etc
configuration file.
3. Change your SLAAC RAs and DHCP servers over to announcing the new addresses
4. Wait until the old addresses are deprecated off the interfaces of all the
clients.
5. Remove the old address range(s) from the servers.
6. Remove the old address ranges from the routers.
7. Disconnect the old ISP
