When system changes occur that result in changing member and/or subscriber IDs, the old IDs should be moved to the Alias fields at the end of each member or claim records. The new IDs should populate the original fields. The System ID field should be incremented by 1 to represent ID changes.

Data users should use the System ID field as a trigger to determine if a member ID changed.
