If you want to retain the extra fields you can

SELECT * FROM tableWithExtraFields INTO CURSOR newCursor
APPEND FROM tableWithMissingFields

The extra fields will be filled with the default value for that data type.

If you want only the common fields you can

SELECT * FROM tableWithMissingFields INTO CURSOR newCursor
APPEND FROM tableWithExtraFields
