A machine may be configured to migrate data among databases. For example, the machine determines a control signal value that indicates a migration state of a migration of member profile data associated with one or more members of a Social Networking Service (SNS) from one or more legacy databases to a consolidated database. The machine accesses member profile data at the one or more legacy databases, and causes a replication of the member profile data at the consolidated database. The causing of the replication includes transforming the member profile data from a schema associated with the one or more legacy databases to a schema associated with the consolidated database. The machine performs a data equivalency test. The machine, based on a result of the data equivalency test, modifies the control signal value to indicate a further migration state of the migration of the member profile data.
