Number your internal network on ULA, and put public addresses on your
machines as well.
RFC3484 support in your OS will cause your machine to use ULA to talk to
other ULA interfaces, and the public IP to the rest of the internet.
If you change ISPs, send out an RA with the new addresses, wait a bit,
then send out an RA with lifetime 0 on the old address. All the machines
should drop their old ISP's IP, and start using the new ISP, as well as
continue using ULA like nothing's changed for the internal file
