LAS formats

I process lidar data and our software outputs it as LAS 1.2. I found recently that USGS and some other government entities will require LAS 1.4. I see that GM will export to this version, but does anyone know if that will be sufficient or will I have to find some way to process directly to 1.4?

    An update if anyone else is interested. It appears one of the format changes from 1.2 to 1.4 involves the location of various flags and the classification of points (32 classes in 1.2 vs 255 in 1.4). To move the classification to the proper byte, an offset has to be added to the initial class.

    Can anyone at Global Mapper confirm this or know how to tell if a conversion from 1.2 to 1.4 in GM does this properly?
