Abstract: Example methods and systems to perform a migration of a virtualized computing instance and its first snapshot hierarchy from a first object store to a second object store have been disclosed. One example method includes identifying a first disk chain of the first snapshot hierarchy having an object running point, identifying a second disk chain of the first snapshot hierarchy different from the first disk chain, and migrating the second disk chain from the first object store to the second object store to form a first branch of a second snapshot hierarchy in the second object store. After the migrating, the example method includes instructing to take a first native snapshot on the object running point in the second object store, instructing to revert the object running point along the first branch and migrating the first disk chain from the first object store to the second object store.

Abstract: System and method for converting a storage object in a redo-log snapshot format to a single-container snapshot format in a distributed storage system uses a temporary snapshot object, which is created by taking a snapshot of the storage object, and an anchor object, which points to a root object of the storage object. For each object chain of the storage object, each selected object is processed for format conversion. For each selected object, difference data between the selected object and a parent object of the selected object is written to the anchor object, a child snapshot of the anchor object is created in the single-container snapshot format, and the anchor object is updated to point to the selected object. The data of the running point object of the storage object is then copied to the anchor object, and each processed object and the temporary snapshot object are removed.
