    Hi hraju,

    Array migration using Mirrors can be done with data access still available to the storage.  There will be some degradation of application performance while the mirror is resyncing.  Symantec does not have any posted data numbers as to what performance degradation you will see.

    SmartMove will help decrease initial synchonzation times of the mirror.  It does this by mirroring only the actual data on the drive using the NTFS filesystem.

    I knwo that we do have many customers that do initial and rescyn mirror operations with live data. 

    Thanks,
    Wally
