Not sure this is the correct group. I placed this question in the CDB group, but got no reply:
In my old schema I had a 'must' statement.
I then changed my schema and removed the must statement.
When I changed the schema in my confd.cdb directory and then restart confd it still yells about this must restriction, and does not let me connect to the cli.
The way I upgrade the schema is by coying the aaa_init-fxs, system-.fxs, aaa_init-.xml, and system-xsd-init-.xml, where the wildcard stands for the version of the schema I just created.
I don't completely understand how the yang upgrade process works, so I am not sure I am doing it right, although I do see my new files in confd.cdb.
