Claim 7:
8. A method, comprising:
receiving, by a system comprising a processor, a request from a client computer, wherein the request indicates a file system operation, wherein the request references a source file handle of a first source file system, wherein the source file handle comprises an identifier of the first source file system, and wherein the first source file system has been migrated to a first destination file system that hosts a group of file systems that comprises the first destination file system;
determining, by the system, that the source file handle corresponds to the first destination file system among the group of migrated file systems based on the identifier of the first source file system, wherein the first destination file system comprises an identifier that is unique among the group of migrated file systems;
determining, by the system and from a source inode number of the source file handle, a source inode number segment, based on the source inode number being determined to be within a contiguous range of inode numbers associated with the source inode number segment, and wherein the contiguous range of inode numbers is less than a total range of inode numbers of the first source file system;
determining, by the system and from the source inode number segment, a destination inode number segment, wherein the second computer maintains respective destination inode number segments for respective migrated file systems of the group of migrated file systems;
determining, by the system and from the destination inode number segment, a destination inode number; and
performing, by the system, the file system operation on the first destination file system of the group of migrated file systems using the destination inode number and the identifier of the first destination file system.
