That depends on how the Challenger was originally developed. If it was originally developed with a commercial aircraft in mind then the move from a corporate jet that MIGHT fly at the most two sectors a day but most likely say 5 sectors a week, to an airliner that WILL do ten sectors a day then you will likely have few problems.
Thats not withstanding what ever modifications were made from the Challenger to the CRJ to make the CRJ a viable commercial airliner.
In the case of Embraer, they have largely of the shelf GA components shoved into a commercial airliner airframe and the results while very good when all is working well is a very glitchy aircraft when even doing the most simplest tasks. But fortunately because they are largely software based aircraft most of the glitches can be programmed out of the aircraft. Its just taking them a while.
