Backup a Query Print Layout or PLD form to restore later

How can I backup a PLD or Query Print Layout and save to a drive that will allow me to restore the layouts later on another version of B1?

I am upgrading 2005 to 2007 and during some testing I found the layouts were not saved in it's original form that we created and we had to redo them. I want to be sure I keep the layout as is and only tweak the fields if they have changed at all from 1 version to the next.

Any ideas?

Thanks
