A data storage system (110, 400) for managing storage of data from clients, comprising: a data storage (114, 150) comprising: an accelerator pool (152, 310), and a non-accelerator pool (154, 320); and a data storage orchestrator programmed to: identify a client assignment update event based on a change in use of the data storage by a client of the clients, make a determination that the client assignment update event is a promotion event, and in response to the determination: promote the client to move a primary data storage of the client from the non-accelerator pool to the accelerator pool, wherein moving the primary data storage of the client from the non-accelerator pool to the accelerator pool comprises: freezing a primary replica (424.2) in the non-accelerator pool, wherein the primary replica is associated with the primary data storage of the client; instantiating a tertiary replica (412.2) in a node of the accelerator pool node by copying the frozen primary replica; updating the tertiary replica (412.4) based on differential storage that occurred while instantiating the tertiary replica; suspending the client's use of the primary data archive (422.2) of the client after updating the tertiary replica; assigning the tertiary replica as a new primary data archive (412.6) of the client after updating the tertiary replica; starting the client's use of the new primary data archive of the client after assigning the tertiary replica as the new primary data archive of the client; and purging the primary data archive of the client. a data storage (114, 150) comprising: an accelerator pool (152, 310), and a non-accelerator pool (154, 320); and an accelerator pool (152, 310), and a non-accelerator pool (154, 320); and a data storage orchestrator programmed to: identify a client assignment update event based on a change in use of the data storage by a client of the clients, make a determination that the client assignment update event is a promotion event, and identify a client assignment update event based on a change in use of the data storage by a client of the clients, make a determination that the client assignment update event is a promotion event, and in response to the determination: promote the client to move a primary data storage of the client from the non-accelerator pool to the accelerator pool, wherein moving the primary data storage of the client from the non-accelerator pool to the accelerator pool comprises: freezing a primary replica (424.2) in the non-accelerator pool, wherein the primary replica is associated with the primary data storage of the client; instantiating a tertiary replica (412.2) in a node of the accelerator pool node by copying the frozen primary replica; updating the tertiary replica (412.4) based on differential storage that occurred while instantiating the tertiary replica; suspending the client's use of the primary data archive (422.2) of the client after updating the tertiary replica; assigning the tertiary replica as a new primary data archive (412.6) of the client after updating the tertiary replica; starting the client's use of the new primary data archive of the client after assigning the tertiary replica as the new primary data archive of the client; and purging the primary data archive of the client. freezing a primary replica (424.2) in the non-accelerator pool, wherein the primary replica is associated with the primary data storage of the client; instantiating a tertiary replica (412.2) in a node of the accelerator pool node by copying the frozen primary replica; updating the tertiary replica (412.4) based on differential storage that occurred while instantiating the tertiary replica; suspending the client's use of the primary data archive (422.2) of the client after updating the tertiary replica; assigning the tertiary replica as a new primary data archive (412.6) of the client after updating the tertiary replica; starting the client's use of the new primary data archive of the client after assigning the tertiary replica as the new primary data archive of the client; and purging the primary data archive of the client.
