Data record correlation and migration

A system comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors, wherein the memory is configured to provide the one or more processors with instructions which when executed cause the one or more processors to:
• receive, at a first application instance from a second application instance, a correlation request for a data record of the first application instance;
• update a correlation index with a directional correlation entry in response to a determination that the correlation request is approved;
• in response to determining that the data record has been modified, utilize the updated correlation index to determine that the modified data record is to be provided for correlation to the second application instance;
• and
• provide a version of the modified data record to the second application instance.

A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

• receiving, at a first application instance from a second application instance, a correlation request for a data record of the first application instance;
• updating a correlation index with a directional correlation entry in response to a determination that the correlation request is approved;
• in response to determining that the data record has been modified, utilizing the updated correlation index to determine that the modified data record is to be provided for correlation to the second application instance;
• and
• providing a version of the modified data record to the second application instance.
