I am just wonder about the mentioned question, at the title. I mean, as a first step of installing TSW5, I would like to have just the 3 routes that comes with it. But at the same time I would like to still have TSW4 installed too. This question is mainly to DTG. My idea is make a first try of the new sim, but still using the previous routes on TSW4 This is due to, I have no enough time to make both things, the same day. Is that possible?
