CentOS - Apr 2010 - Disc Cloning Question

I have a server with a stock install scheme with the exception that /boot and
/ are on two md raid 1 mirrors over two discs.

I need to remove those two large discs and replace them with smaller discs.

Given the lvm over md, and big to small scenario, anyone know any automated
app that can do this?

I don't want to spend the time to resize the ext3 partition, the vg etc and
re-mirror manually...

Thanks!

Even if there is a way to do a live migration, it's probably faster and 
safer to just build a new raid with or without lvm and copy the stuff 
over.  You'll just have to reinstall grub on the new disks to make them 
boot.
