Is there a way to import data from another SAN (Dell Compellent) to EMC VNXe3200?

I've been using vSphere Storage Migration to move the data, but cannot Storage vMotion Physical Raw Device Mappings. I was wondering if there is a way to migrate data into the VNXe.

I can't be the only one who has this issue, but I can't find any support threads on this process, if its even possible at all.

Any ideas?
