SLP Duplication from MSDP to MSDP

Good Day Geeks !

We are duplicating our remote backups to a central hub . We have netbackup appliances at local sites to which we are duplicating to MSDP pool which we created on one of our Linux boxes.

Now we have purchased aan appliance at central hub site and want to move all our remote backup duplications to appliance.

Now if i just put appliance storge unit in SLP duplication ,it will duplicate all the dta over the WAN which I am not looking for.

Any way I can seed the data from my old pure disk pool to appliance so when the duplications start ,it will only send meta data and the changed data over the wan.

Thanks,
