No, D-Star does not automatically switch between analog and digital. You have to have one channel set up for analog and then if you want to do digital on the same frequency, you have to set up a digital channel. P25 can monitor both analog and digital in mixed mode operation but only transmit in one or the other (so you need to channels on a P25 radio as well for transmit purposes.
