Milk protein intolerance swapping from powder milk to soya instead of cows milk

My son is cows milk protine intolerant.. Really unsure about what I'm doing and scared I'm doing the wrong thing so just posting this so maybe some mums that have a child with this can help me out here because I'm clueless.. Dietitians told me to swap my son on to soya milk.. I am understand that other children get swapped on to full fat cows milk at around 12 months so I take it the soya milk is my sons alternative to that.. I will put pics below but have I baught the right soya? It says it can only be used as a milk alternative from 2 years? Do I just give him this soya and stop giving his other milk and only offer the soya? If you can help please do I'm a very confused mummy lol
