Does Izotope Music Production Bundle 2 Upgrade Overwrite Presets? (Answered)

Does Izotope Music Production Bundle 2 overwrite  Music Production 1 user presets when installed ?
 
Thanks in Advance,
KM

Thanks Larry.
 
That's exactly my thought pattern.
Just trying to avoid running into an issue with projects that already have MPB1 on them.
 
Depending on the verdict from Izotope, I could definitley figure out a workaround, which would be more tedious.
I'll give the verdict here from Izotope, when I get it (contacted and waiting for response).
 
Thanks again Larry
 

Thanks  Simeon.
OK,
with that, I think I am going to jump in (bite the bullet and run the upgrade).
I'll report/confirm results.
 
Thanks guys!
