Abstract
A computer system may provide zero-downtime, reversible, client-driven service migration to migrate a client from a current service to a new service. The computer system may configure the client to operate in a dual-write, old-read mode in which the client issues write requests to both the current service and the new service and issues read requests only to the current service. The computer system may configure the client to operate in a dual-write, new-read mode in which the client issues write requests to both the current service and the new service and issues read requests only to the new service.
