EXPERT RESPONSE
Since long (raw) will be going away, in future releases of Oracle database, I would recommend that you convert your Long Raw to a Blob and your Long to Clob. Then you can migrate your table to another schema within the same database release or to a higher database release.
The following statement will convert your long raw to a Blob:
ALTER TABLE long_tab MODIFY ( long_col bLOB );
Where the column long_col was a long raw datatype converted to a blob datatype.
Here's some more information on the advantages of using a lob over a long raw.
