Hi,
We are planning for storage Migration from EMC utility 2 to utility 3 storage, all the filesystem are vxfs we are planning to mirror the old disk and new disk and sync the data and remove the ...

The new LUNS do not need to be the same size. Normally they would be the same size or bigger, but they just need to be big enough to mirror your volumes onto, so if you have a lot of free space in your diskgroup then you can make your new LUNs smaller.
A few commands to help you:
Show volumes and their sizes: vxprint -v
Show Volume Manager disks and their sizes: vxprint -d
Show free diskgroup space: vxdg free
All of the above, can of cause be used with "-g diskgroup" if you want to view for a particular diskgroup.
If in doubt - post the output of the above commands
Mike
