Hi Chen, You can try transportable tablespace (TTS) for this. Partition
your source data and move newer data to new tablespace and transfer it to
destination. This method would be much faster than datapump export/import
Thanks,

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.

Hi,
Our company needs to migrate some databases to new servers.
However we don't want to migrate the whole databases, which have years of
old data. Rather, we want to select some newer data from some tables and
only carry these over to the new databases.
Export and import will take too long due to the large sizes of our
databases.
Physical Standby won't work. Is logical standby an option here?
I am also considering using GoldenGate.
Are there other options?
Thank you,
Chen
