Datapump can subset data - you provide a query to DataPump to pull out the
data you want to export and import into the new database.
You could at least do a POC (Proof of Concept) of datapump to see how what
that can get you . You can use parallel on the datapump to speed things
up a lot.
You could combine Datapump subsetting and GoldenGate I think - subset your
data and use Golden Gate to sync up the SCNs (CSNs in GoldenGate) to keep
the new data up to date if I'm not terribly mistaken.
