I don't think that the two have to be the same, unless you made them the same.

In any case 'cryptsetup -y luksAddKey /dev/sdaX' allows you to add a 
passphrase in another slot - can't recall how many passphrase slots are there 
without looking into it.

Reboot to make sure it works and then use luksDelKey 0, to remove the previous 
key from slot 0.

Also, check gnome-disk-utility which I think allows you to change the 
passphrase.

I don't use gnome or luks at the moment, so someone with recent experience 
should chime in and put me right.
