This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Can we get region and carrier information, in order to answer this more effectively? Basically the three easy options are OTA, ODIN or Kies, though. –  Jeeva Jul 6 '12 at 8:45
    
I'd consider only OTA and Kies as "easy", especially as the question is this vague. Plus, he's asking for official documentation, so warranty might be a factor. –  onik Jul 6 '12 at 12:58

I assume your device is not rooted since you did not mention it. For non-rooting device you just have to wait for the Over The Air (OTA) update from Samsung or your network provider.

Official documentation can only come from your carrier, or if you bought it sim-free, then from your country's Samsung website.

Ota is definitely going to be the "easiest" but you aren't guaranteed to ever get the update. If you want to get ICS as soon as possible, I'd recommend flashing CyanogenMod (full update guide for the S2), downloads are here. Believe version CM9 is ICS 4.0.4, and CM10 (aka. Jelly Bean) is also available as nightly builds. I've heard some great things about it.

But... that may not be what you are looking for if you are trying to go completely stock...
