Thanks David,

I want to replicate the data once it reached on the cluster, and delete
from source Cluster after one year. I want Cluster works as Hot Backup and
Archival and Cluster A only having latest data.

And as per my information distcp copy all the data and over-right. Please
correct me if i am wrong.
