Hi We have a CX3-40with 8 DAE shelves (7 x DEA3P and 1 x DAE2P)  We want to hear whether it is possible, to set a CX-4PDAE DAE4P with CX-4G15-600 600GB 15K to the CX3-40.  Or do we need to upgrade the CX3-40 to CX4. Is it possible to upgrade the CX3-40 to a CX4?  We talked with EMC and they are saying that is impossible and we read here that it is possible..  Thanks! Infare
