For a master/slave backend combination they need to be the same main
version and they will share the db on the master backend. So if as I
assume your old backend is an older version? You can't without
upgrading. If they are the same version and you have brought over the
db to the new backend, I think all you have to do is point in the
setup on the old backend to the new backend for master and db. To make
sure it doesn't use the old db on the old backend, make sure mysql is
not running there. Resources like tvcards and storage is always linked
to the hostname, so that should all work.
