MGTCA-01204
The name supplied to -oldClusterName '{0}' is not found in the GIMR records.
Cause
An attempt to execute 'mgmtca' to update the cluster name property of the Grid Infrastructure Management Repository (GIMR) failed because the indicated name specified as the 'old cluster name' did not match the current cluster name property in the GIMR.
Action
Verify the old cluster name stored in the GIMR is the cluster name prior to the cluster rename and retry the operation specifying the correct old cluster name.
