If your game is version 0.8.0 or later then there is an auto-update feature already in place. It will simply say something along the lines of, "There is a new update available! Would you like to download it?" Just click yes and it will be downloaded and put in place.
I am assuming that your game is earlier than that version and since it is, then I'm just gonna reword theonethetwothefour's reply. Go to the settings, click the "Open Data Directory" button, open the "saves" folder, and copy your clan folders. Then, open the data directory in the new Clangen game, go to the saves, and paste the saves there again.
I am a bit confused on why you couldn't find a save folder. Can you list the folders you see? I have four folders, "~temp", "cache", "logs", and "saves". I haven't seen a Clangen game that old so it could be different. Hope this helps :)
