I must admit that I too was a little concerned on my transition from conventional to glass. Also from Boeing to Airbus, but that is a different kettle of fish altogether. You will find that glass greatly enhances your situational awareness and makes flying easier as all the info you require is on two displays. It will take you one simulator session and you'll be OK, the FMS/FMGS work takes a little practise but thats to be expected.
Have fun. Which company is it that you're gonna work for?
