Regarding usermapper database in VNX.

Hi,

I am migrating a VDM from one of the Celerra NS-40  to VNX8000.  The user mapper database already exists in the VNX box. What will happen if I export and import the Usermapper database from NS-40 to VNX8000. Will it get updated or over-written?

Please let me know the procedure.

Thanks,

Sivas.
