Porting BLOB data from one tablespace to another

How can I port a .dbf file containing BLOB data in one tablespace to another tablespace? I have exported the file "page.dbf" (this file contains BLOB information) from tablespace "development." Now I need to import this page.dbf to another tablespace "production." The export and import tools will work best. This BLOB data resides in a table. So you'll want to export that table's contents to a dump file. Then transfer the file to the...

other server and use the import utility to move the table into the other tablespace. You may have to precreate the table in this new tablespace and import with IGNORE=Y. This assumes that the tablespaces are in two different instances.

If the tablespaces are in the same instance, then you can move the table to a new tablespace with the ALTER TABLE MOVE command.
