How to get from continuous time to discrete?

I have a dynamic model implemented in simulink, and I have to discretize it and compare the results. Am I allowed to replace the integrating blocks (1/s) with discrete blocks (1/z) ? Do you have any other suggestions?

1/z and 1/s are NOT equivalent. 1/s is an integration while 1/z is a delay, totally different. You can use the model discretizer to get started, but it sounds like you should read a bit more about digital control first.
