Is the scanpst.exe that came with Outlook 2007 same as that of 2003?

Scenario:
my current laptop runs outlook 2007 on Vista. I need to check several
pst files using scanpst.exe. I planned to copy my pst files to another
computer and check it there so I can continue to work without any
performance degradation on my current laptop while the other PC scans
the pst in parallel.

However, the other PC runs outlook 2003 on XP. If they're not the same
versions, can it check OL2007 pst files or will it corrupt them?

Thanks.
