1. A method for accessing an object in a storage network, comprising: receiving a NAS (Network Attached Storage) file handle for the object including a location of the object on a source file server; sending to a client as representative of the object, a switch file handle for the object that is independent of the location of the object; migrating the object from the location on the source file server to a location on a destination file server, wherein the migrating comprises replicating a namespace associated with the object, the namespace located on the source file server and the replication of the namespace occurring separately from migrating data associated with the object; receiving from the client an access request associated with the switch file handle; mapping the switch file handle to the NAS file handle; and sending the access request to the location on the destination file server using the NAS file handle.
