EVA to DMX-4 data migration

I want to migrate approx. 4tb of data currently residing on a HP-EVA over to a DMX-4. My plan is to zone a second HBA on the hosts to the DMX and allocate a dev, and then copy the data. my concern is that the copy will not finish before the maintenance window closes.
Does anyone have a suggestion for copying the data, I know EMC use to have a copy utility that would keep the data available to users and when the copy was complete reboot the target and rename the drive letter.... any suggestions would be appreciated..-thanks

    Have you looked at Open Migrator. It is available for UNIX as well has Windows.

    And what about the good old host based mirroring ?
    Create LUN's on DMX and mirror them with any LUN from the EVA and have each host perform mirroring of the data. After that is done, break the mirror and remove the EVA LUN's.

    Windows includes a "basic" volume manager (straight from Veritas/Symantec). And it looks like it offers mirroring (amongst other) capabilities..

    i know it works for dynamic disks, if somebody figured out how to mirror basic disks without using third party tools i am all ears :)

    I guess it's also stated in the solutions I posted .. mirroring works only with dynamic disks. :D

    I will need to make the target larger than the source , I believe to use windows software mirroring both disks have to be the same size, if not the target will assume the source size.... I may be wrong.

    I'm absolutely not a Windows person, but it's software mirroring, just like any OS can do. Even Windows can do software mirroring of 2 disks. I know Windows versions up to 2003 could do this....

    Ah ok, I knew it was possible, but didn't know of any restrictions ;)
