1. A method comprising:
determining a control signal value of a control signal attribute based on accessing the control signal attribute at a record of a database, the control signal value indicating 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 control signal value being associated with one or more member identifiers of the one or more members; at a time indicated by a timestamp associated with the control signal value,
based on the one or more member identifiers associated with the control signal value, accessing member profile data associated with the one or more member identifiers at the one or more legacy databases, andcausing a replication of the accessed member profile data at the consolidated database, the causing of the replication including transforming the member profile data from a first schema associated with the one or more legacy databases to a second schema associated with the consolidated database; upon the causing of the replication of the member profile data at the consolidated database, performing, using one or more hardware processors, a data equivalency test based on the member profile data at the one or more legacy databases and the member profile data at the consolidated database; and based on a result of the data equivalency test, modifying the control signal value to indicate a further migration state of the migration of the member profile data associated with the one or more members. |
