Why don't you try Asycronius SnapMirror between filers? Once trasnfer is completed, in a planned maintanance window, do Snapmirror Update, Unmap the original LUN, Mapped the New LUN from the Other Filer and continue on your normal business work

agreed...best way to go. Also run "lun serial" to get the lun serial number to apply to the new location so the serial number is the same. Depending on the OS there can be some troubleshooting when the lun has a different serial number so when we snapmirror luns for a migration we make sure the target has the same lunid and serial number and the host just works when it remounts.

you mean to say copy theVolume on which the LUN residing right i mean
vol copy -S filer1:/vol/vol1/Lun1 filer2:/vol/vol1/Lun2
Will this command do ??? else what if i want to migrate only the Data from the LUN in filer1 to filer2 LUN

You don't specify LUN path, just the volume.
If you want to migrate data only, you need to create target LUN first and then move the data via host, when both LUNs are connected.
