In ArcMap 10, after importing an ArcView 3 project with broken data sources, ArcMap does not allow the user to redirect those broken paths to another file.
Open the apr with notepad, or any text editor. While looking at the apr through notepad, you can find the file path that is currently set, and change it to the location of the data on you current machine.Right-click the .apr > Open with notepad > Edit Menu / FindSearch for "path" (without the quotes)For each layer in the map their will be a path for the .shp and a path for the .dbf, you will have to change both.For example, if you open a apr in notepad and search for path, the first place that it should take you is:Path: "g:/orange ave corridor specific plan.shp"and next you will find...Path: "g:/orange ave corridor specific plan.dbf"You would need to replace these paths with the new location of the data. After doing this for each layer, save notepad and close. Then you can open a new mxd, set the reference scale, and import the apr. You should find that all your layers will be sourced correctly, and the labels are closer to what they were originally.
