Updating Point elevations & profiles

HI guys, running 2007 SP 3 Civil 3d.

Got a really good question for you all. I had some points that our surveyors gave me last week that were on the wrong datum. Way off some 900 feet. I didn't know this at the time, and I created a surface, alignments, profiles and a Corridor off of these points.

Yesterday my surveyors went out, gathered some more needed survey points and adjusted the datum on all of the points, new and old.
So I deleted my old points and corrisponding point groups. Added in the new points and placed them into a point group, rebuilt the existing surface so that it now reflects the 900 elevation mark and new datum. But what I have discovered is that my profiles did not update, the EX Ground on my profiles updated and is no longer visible in my profile views but my Future grade never update the 900 foot difference. How do I fix this?

I know it's probably something really simple that I over looked, would love you help on this little one thanks.

Never mind, I figured it out.

In case you need to know, go into Profile Properties on the future profile and move all PI's to the difference in the new elevation versus the old elevation.

Duh!!, what a blonde moment.
