how can i make the game saves move to the next version? i don't want to lose my progress, do some copy paste or something like that ?
In most cases, you can just copypaste the entire save-folder in "Small On Top/www" from the previous version into the next one (the config and global-file are also important). However, RPGMaker can be a fickle program when it comes to loading older save files in a newer version with new scripts and stuff. If you're upgrading from 0.17 to 0.18 (or from 0.61 to 0.62 if you're a Patreon), you should be good to go, but in other cases, you might have to use a save file from before you first entered the freshly updated areas (it's always good to keep a save file where you haven't entered Piratetown yet, as that's the area where things become WIP in the game).
