The metric backend configuration file etc/check_mk/metric_backend.json contained the site name (in the TLS server hostname and the mTLS certificate paths). Since omd mv and omd cp do not update this file, connections to the metric backend failed after renaming or copying a site.
These values are now derived from the site instead of being stored. Existing configuration files are read transparently; no manual action is required.
