The achievements stay between versions. The normal save data however has a chance to bug out, so I run a check to see if the versions are consistent. If you really want to force an old save into the new version, locate the save files under *Username*\AppData\LocalLow\Impy\Sweeper and change the game version in settings. Do so at your own risk, I do not guarantee any type of good result.
