 Division I is split into two groups of six , both groups play in round robin tournaments independent of each other and the championship division . Previously the top team from both groups was promoted to the championship , while the bottom team was relegated to Division II . Beginning in 2012 , the top two teams from the ' A ' group will be promoted to the championship , the bottom team will be exchanged with the group ' B ' winner , and that group 's last place team will go down to Division II .
