It's certainly possible, but it requires a few steps. You'll need to bring the Expression (version 2 or above) file into the Expression Offline Editor, and do an ASCII export. You can then transfer that to the Eos, and import the file. An ASCII import/export has its limitations, but it gets all the basic cue data (levels, timings, etc...). As with any show data that goes from one console platform to another, you'll want to check things a bit to make sure all the data came through.
