Abstract
A data object may be moved from a source data store to a destination data store via replication. The replication is initiated when an original data object in a source data store that is capable of being both read from and being written to is read. Following the read, the original data object is then duplicated to a destination data store. The duplicate data object is provided with a state that indicates the duplicate object is duplicated from the source data store and can be read but cannot accept a data write. Subsequently, the state of the original data object is changed to can be read but cannot be written to using optimistic locking. Further, the state of the duplicate data object is also modified to being capable of both read from and written to with the use of optimistic locking. The replication is completed with the deletion of the original data object from the source data store.
