When no database is specified, frontends and backends alike will attempt to find the master backend using UPnP.  When successful, they then query the master backend for the database credentials it is using, and try to use that themselves.  The PIN number you can configure in mythtv-setup is intended to prevent auto-configuration from hooking into the wrong cluster.  A PIN of 0000 turns off protection, and allows anything to query those credentials. An empty PIN disables auto-configuration entirely, and allows nothing to query those credentials.

So is that the correct way to build a new replacement BE while the old BE is in operation (or alternatively to have a test BE and a production BE)? Clear the pin from all BE's and just make sure the FE's have the correct configuration present? Like the OP I want to have two Master BE present on the network - at least until cutover. Once cutover I was half thinking of keeping the old BE as a testbed provided it wasn't going to cause me undue problems.
