Migrate CX lun to VNX using mirrorview and clone

Hi all

I need to migrate a SQL cluster Luns from CX-480 to VNX

At this moment we've got 2 CX 480 with mirrorview/S and MV/CE for SQL cluster luns.

All luns are replicated with MV

CX4-480_1_lun_X -> mirroview/S -> CX-480_2_lun_X

CX4-480_1_lun_Y -> mirroview/S -> CX-480_2_lun_Y

....

I want to create a clone for CX-480_2_lun[X-Y], and replicate this clone with MV/s o VNX

CX4-480_1_lun_[X-Y] -> mirroview/S -> CX-480_2_lun_[X-Y]

                                                                           |-> clone -> MV/S -> VNX_1_lun_[X-Y]

1. Is it possible this kind of migration.

2. MV/CE could cause some problem for this kind of migration

Thanks

Matteo
