This will show you the table for chained rows, not sure if it covers migrated or not, anyone else?
select owner, table_name, chain_cnt from dba_tables where chain_cnt > 0;
You can have it: Fast, Right or Cheap, pick 2 of the 3. Fast + Right is Expensive
Fast + Cheap will be incorrect.
Right + Cheap will take a while.

Please respond to maheswara.rao_at_ubs.com
In my database when I run the following query against v$sysstat, I find huge number of migrated/chained rows.
SQL> SELECT name, value
FROM v$sysstat WHERE name = 'table fetch continued row'; NAME VALUE
table fetch continued row 2327441
How do I find to which table these migrated/chained rows belong?
