ORA-14296: Table block size mismatch in ALTER TABLE EXCHANGE [SUB]PARTITION

What triggered the Error:

The block sizes of the two tables specified in the ALTER TABLE EXCHANGE [SUB]PARTITION statement are different. For index organized tables, either the block sizes of the index or the overflow (or both) do not match.

What should we do to fix it:

Ensure that the block sizes of the tables involved in the ALTER TABLE EXCHANGE [SUB]PARTITION statement are the same. For index organized tables, ensure that the block sizes of both the index and the overflow of the two tables match.
