Data store transition using a data migration server

A data migration server, comprising:

• at least one processor;
• and
• a non-transitory, computer-readable medium having instructions stored thereon that are executable by the at least one processor to cause the data migration server to:
• access data stored on a preexisting data store to service requests from a plurality of services, the preexisting data store being designated as a primary data store to service the requests;
• enable a dual-write operation mode for the data migration server such that, in response to a given write request from one of the plurality of services, the data migration server is configured to write a given data entry to both the preexisting data store and a replacement data store that is configured to store data used by the plurality of services;
• enable a dual-read operation mode for the data migration server such that, in response to read requests from the plurality of services, the data migration server is configured to read corresponding data entries from both the preexisting data store and the replacement data store;
• facilitate data verification operations to verify that data read from the replacement data store matches data read from the preexisting data store during the dual-read operation mode;
• and
• modify configuration settings for the data migration server to designate the replacement data store as the primary data store used by the data migration server to service requests from the plurality of services.

A non-transitory, computer-readable medium having instructions stored thereon that are executable by a data migration server to perform operations comprising:

• accessing data stored on a preexisting data store to service requests from a plurality of services;
• enabling the data migration server to write data to both the preexisting data store and a replacement data store such that, in response to a given write request from one of the plurality of services, the data migration server writes a given data entry to both the preexisting data store and a replacement data store that is configured to store data used by the plurality of services;
• enabling the data migration server to read data from both the preexisting data store and the replacement data store such that, in response to a given read request from one of the plurality of services, the data migration server reads a corresponding data entry from both the preexisting data store and the replacement data store;
• providing data read from both the preexisting data store and the replacement data store to a data verification system to verify that the data read from the replacement data store matches the data read from the preexisting data store;
• and
• modifying configuration settings for the data migration server to designate the replacement data store as a primary data store to be used by the data migration server to service requests from the plurality of services.
