Need to move the swap partition to another disk

My ubuntu installation and swap file are on the same disk (160.0 GB).

I would like to move the swap file on the little disk /dev/sda
Thank you for your help

So the first step is to shrink the /dev/sda partition to create unallocated free space (i don't want to delete existing partition) ?
That's not a linux boot partition but it is the XP boot disk; Linux is on /dev/sdb

i have grub2 at boot. do you think that changing the partitions setup will compromise my system ?
