Abstract
In one embodiment, systems and methods for performing asynchronous local migration of metadata between data stores and asynchronous remote replication of metadata between sites are described. The methods may use various configurations, including 1-to-1, 1-to-N, N-to-1, M-to-N, etc. The method for performing asynchronous local migration at a first site may include pausing critical operation(s) at an old data store, copying metadata from the old data store to a new data store, flagging table(s) in the old data store as complete, and deleting the metadata from the old data store. The method for asynchronous remote replication may include determining that local migration is complete, identifying second metadata from the new data store for which the first site is a primary authority, sending, to the second site, the second metadata, receiving, from the second site, third metadata for which the second site is the primary authority and storing the third metadata.
