Abstract
A system can perform a migration. The system can, in response to receiving a request to perform a file system operation on a destination file system, wherein the request identifies a first source file handle, direct, by a second computer and to a first computer, to perform the file system operation on a source file system with the first source file handle, to produce a second source file handle, convert the first and second source file handles to corresponding first and second components of a destination file handle, perform the file system operation on the destination file system with the first and second components of a destination file handle, respond to the client computer with the second source file handle. The system can re-assign a network address when rolling back the migration, wherein a client is configured to use the second source file handle with the source file system.
