i know with thick devices you have to match config layout, but could be that thick to thin requirement is still the same. I guess next thing i would try symclone to striped thin.
I have a VMAX where I want to clone from a STD META (native provisioned) to a THIN META.  Microcode Version (Number)           : 5874 (16F20000)Microcode Registered Build           : 4Microcode Date                       : 05.04.2010  Microcode Patch Date                 : 05.04.2010Microcode Patch Level                : 229  Symmwin Version                      : 182  I get this when I try to do a:  symclone -sid XXXX -f pairing.list establish -consistent -full  Devices: 034A(S) - 08B2(T) [(M) NOT PAIRED - META CFG MISMATCH]   Both devices seems to be configured the same from a config perspective:  034A: Device Capacity    {     Cylinders            :     297440    Tracks               :    4461600    512-byte Blocks      :  571084800    MegaBytes            :     278850    KiloBytes            :  285542400    }  Device Configuration     : RAID-5          (Meta Head)  08B2: Device Capacity    {     Cylinders            :     297440    Tracks               :    4461600    512-byte Blocks      :  571084800    MegaBytes            :     278850    KiloBytes            :  285542400    }  Device Configuration     : TDEV            (Meta Head)  Any thoughts?
