Abstract: Storing a data storage object in a first data storage system that uses object IDs with a first object ID format includes determining if the data storage object was created on a second, different, data storage system having a second object ID format different from the first object ID format or created using an emulator of the different data storage system, using a lookup table to translate between the first object ID format and the second object ID format in response to the data storage object having been created on the different data storage system, and directly converting the object ID to a new object ID having the second object ID format without using external data. Directly converting may include converting at least a portion of the content of the data storage object into at least a portion of the object ID.
