No, you can not upgrade your Samsung Galaxy Ace Duos to Android 4.0 (Ice cream sandwich) or 4.1 (Jelly Bean). There is no official announcement for this and the phone still runs on old Android 2.3 Gingerbread.
But with the help of CyanogenMod 10.1 which is a custom ROM, Galaxy Ace Duos can now be upgraded to Android 4.2.1 Jelly Bean. But remember this is not official and Samsung does not support this and this may damage your device. So, it is not recommended.
