Abstract
In general, the invention relates to a method for migrating a source file system residing on a source server to a destination server. The method includes sending a first snapshot of the source file system from the source server to the destination server and creating, using the first snapshot, a migrated file system on the destination server. The method further includes sequentially sending, to the destination server, a set of snapshot deltas including modifications to the source file system, updating the migrated file system using the set of snapshot deltas, determining that a freeze threshold is exceeded, freezing the source file system, sending a final snapshot delta from the source server to the destination server, updating the migrated file system using the final snapshot delta, creating a file system husk referencing the migrated file system, and thawing the source file system and the migrated file system.
