Or do a CTAS across a db link using parallel DML (destination) nologging and
parallel query (source) and save UNDO. Create indexes in parallel mode
nologging.

Either EXPDP from the source database, or IMPDP from the destination database,

from being wasted on writing to and reading from intermediate ".dmp" files.
