They have changed them they are a couple inches shorter and the pieces are slightly different and the motor is a totally different design, but overall they are similar, that one is 230, the latest is 230/3 and this is being replaced by another redesign this year. The 235.02 could not be converted to a Stream as it has a very different pump design. It could be changed to a 3000 powerhead which does about 800gph.
