Here is a skeleton for one possible solution:
Code:
#!/bin/ksh
IFS='|'
while read mBefore mAfter; do
  if [[ "${mBefore}" != "${mAfter}" ]]; then
    echo ${mBefore} | sed 's/,/|/g' | read mB1 mB2 mB3 mB4 mB5 mB6 mB7 mB8
    echo ${mAfter} | sed 's/,/|/g' | read mA1 mA2 mA3 mA4 mA5 mA6 mA7 mA8
    if [[ "${mB1}" != "{$mA1}" ]]; then
      echo "Field 1 was changed."
      echo "Before: ${mB1}"
      echo "After: ${mA1}"
    fi
  fi
done < Input_File

Change it according to your requirements.
