To be clear, you have two clusters, and you're interested in moving a
table's data but not necessarily it's operational load? There is probably a
migration path involving table snapshots, though I've not tried it myself.
It would look something like the following:
- major compact the table to ensure it's data files are all HFileV2
- create a snapshot of the table
- export the snapshot to a path on HDFS
- copy the export to the new cluster, probably with distcp or webhdfs
- import the snapshot into HBase on the new cluster
I have limited experience with the snapshot features, so I may be missing
some steps.
Good luck,
Nick

Can you give a bit more detail ?
Are you migrating whole cluster or just selected tables ?
