I think tool is actually really good. I used it twice for Cisco conversion and worked fine both times. One odd thing I found, but not real sure if this is just cosmetic or way tool works...for example, if you run show runn on Cisco from enable mode and then output it into text file, conversion may not work right, so what you need to do is go to conf t mode on Cisco, run pager 0 and that will eliminate "page breaks" when running any commands, so you dont need to keep pressing space bar on your keyboard.
Anyway, thought would share this, if anyone else encountered this problem.
