All I have to say is ...

Amazing!

I wanted to post this message just in case anyone else was being discouraged from upgrading after reading about the problems on the forum. I just completed an upgrade from 7.0.2 to 7.5.1 and it completed absolutely problem free! Wonderful, I was so apprehensive that something, even minor, would fail and render my server unusable... Not so, everything is functioning as before and the new features are superb.
That installation script seems semi-sentient to me, is there something you're not telling us plesk?
Just wanted to give credit where credit is due!

To plesk 7.5.1? Do you mean 7.5.3?

7.5.1's old, buggy, and not really available now ... if you mean 7.5.3 then cool.

oops, typo there, yes, I meant 7.5.3 ...
