ServiceDesk 7.5 Group Support II does not exist

We were on 7.1 and recently upgraded to 7.5.  We were not using 7.1 for ServiceDesk and I have recently been tasked to set up 7.5 for our environment.  I have read the documentation on ServiceDesk and some of the forums where everyone talks about the Group Support II.  I have no such group and can't find any documentation on making the group appear.  Does anyone have any suggestion?
