Converting from NAD83 to WGS84

An engineer trying to learn how to be a surveyor here... I just completed a mapping of 35 miles of track at the TTCI site. I projected the data to NAD 83 CO state plane, geoid 09 and scaled to ground so as to calculate some new points based on the data. Now, my customer wants coordinates in WGS 84 and I cannot go "backward" with
Trimble business center. Some of my surveyor friends have suggested that if the customer is requesting WGS 84, then they have no idea what they are talking about. That being said, I want to try to give them what they want, but all that I can give them now is the data in the NAD 83 datum. I looked at the NGS website and it doesn't seem like there in a version of the HTDP tool that will transform NAD 83 to WGS 84.

Any suggestions or advice?

Mapping Center Answer:

Using ArcGIS (in either ArcMap or ArcCatalog), you can easily convert from one coordinate system to the other.  Simply use the Project tool with the coordinate systems you want to use.  Here is a link to the online help topic for the Project tool.
