updating older sessions?

[Marvin the android]

HI,
i have an external read/write hard drive with sessions saved in 5.2 format from my old g4 tower 001 setup.

I now have a macbook pro / 003 setup on LE 8 & i wish to update & save the older sessions into 8 format.

My concern is how best to do this.. I assume that i would open the 5.2 files from the old read/write drive in LE8 & then save them to another different drive.. but how do i make sure all the audio files are copied across with the updated session? (so that i know it is then safe to erase the older drive & start it off fresh...of course backing up the 5.2 sessions to dvd first..)

thankyou
