Is it possible to move a CX3-120 DAE and disks to a CX4-240?
Absolutely, both arrays support DAE3P/DAE4P so you can add a CX3-20 DAE to a CX4-240 system, You will need to set the enclosure address on the CX4 array once you add the DAE to it. You will need then to reboot management servers on both SPs to make the CX4 identify the new DAE
Hope it helps

Refer to KB article emc154373 "Which type of Disk Array Enclosure (DAE) can be used in CX4-Series, CX3-Series, and CX-Series storage systems?"
Array Model Type / DAE Type | CX200/400/600 | CX300/500/700 | CX3-10/20/40/80 | CX4-120/240/480/960 |
DAE2 | Yes | Yes | Yes | Yes *6 |
DAE2-ATA | Yes | Yes | Yes | Yes *6 |
DAE2P | No | Yes | Yes | Yes *6 |
DAE3P (DAE4P) | No | No | Yes | Yes |
6: May require that SPs be rebooted for drives to come on-line.
