Digi003 with PTLE 6.4 issues??

I currently use Digi001 with ProToolsLE 6.4 on WinXP. I am thinking of getting a Digi003 with a Win7 laptop (Firewire) so I don't have to lug around my desktop that I currently use.



Will I be able to open my PT files with the versions that the Digi003 uses? I think its PTLE 8 (I don't have it though)



Thanks for any help,
