How to do WAN optimized replication for NetVault backup & Qorestor?

We have a env: 1 netvault backup server and 2 qorestor (1 on local and 1 on remote),

there are 10TB backup data in local, and will transfer to remote site, can I using replication seed to do this?

BTW: I cannot do replication for RDA container, only can using netvault datacopy.
