That should work. In general, the controller only needs the database and
some basic configuration information to figure out how to connect to it.

Unless you have changed some critical information inside the database,
such as e.g. the bind address of one of LINSTOR's NetCom services, to
something that is node-specific, you should not need to change anything
else when you move the controller.
