The Code Conversion Utility renamed a type definition because it found one or more type definitions with the same qualified name. The Code Conversion Utility disconnected all instances of this type definition because it could not link the instances to the appropriate type definition.
Review the disconnected instances in the converted code and link them to the appropriate G Types. Alternatively, you can rename type definitions in the original source code and convert the code again. If multiple projects have type definitions with the same qualified name, convert those projects separately.
This message can also occur if references to a type definition get out of sync with the type definition. Mass compile the files in the version of LabVIEW you used to create the files to ensure references are correct.
