hp-ux

I'm looking to transfer data across 2 lv of an HP-UX server. I have a couple of those transfers to do, some of which are mostly binary (Oracle tablespace...) and some others are more text files (logs...). Used data size of the volumes is between 100Gb and 1Tb. Also, I will be changing the block size from 1K to 8K on some of these partitions...

Things I'm looking for:

Guarantees data integrity
Fastest data transfer speed
Keeps file ownership and permissions

Right now, I've thought about dd, cp and rsync, but I'm not sure on the best one to use and the best way to use them...
