autocad to Miscostation export

Greetings,

Am about to work on Corp of Engineers project and they spec that output is to be in Microstation format. Am using Prosteel by Bentley in Autocad 2010. I am  aware that Autocad has an export function to prpoduce .dgn files. My questions are these. Is this a good, clean translation and are there any known glitches? Any special adjustments required in Autocad required to make the export better? Any special font requirements? Line types, etc??

One last questions, is Microstation offered in a "light" edition?

Thanks in advance for any suggestions.
