A system and method provides for querying and setting file attributes between Network File System and Common Internet File System network attached storage systems. Aspects of the present invention may be performed by a storage virtualization system that acts as an intermediary between one or more network attached storage systems. By querying and setting file attributes, files may be migrated between network attached storage systems while keeping the file attributes and primary location of the file contents intact. In addition, the present invention provides an additional aspect of ensuring that file names of multi-protocol files are compatible across every protocol.
