Everyone who answered you is wrong I'm afraid. ICS isn't available for the Ace 2. The device skipped ICS and went straight to Jelly Bean.
As for unofficial ROMs, you might find some but I wouldn't recommend them as they'd just be homebrews. There is no Cyanogenmod for the Ace 2 as of yet.
THERE ARE UNOFFICAL ROMS available from CWM, try 10.1 for i8160 or 10.2 or 11.0 version's available for aceII on XDA devolpers...
