Is it a one time operation or continuous one ?
If it is a one-time operation, the steps suggested below should work.
Otherwise, you need to set up a process which will continuously feed the source and
apply changes in the destination. Let me know, if this is the case - we have a
similar requirement in facebook, and have set up a replication process (which is not
open-source), but I can tell the main design points.

This assumes you are not going to edit anything while moving.

Is this possible? What's the best way to do it? The hadoop/hive/derby
versions are the same.
