Hi Sumit,
no, this information is not persisted in a transparent table (only temporarily during the migration/upgrade process).
You can of course see the list of tables which have been depooled/declustered in the corresponding dictionary log files (don't know which exactly it is, I'm not an upgrade expert). You might have a look at the logs for table DOKTL (one of the standard tables which I know have been declustered).
Cheers,
Jasmin
