I cannot find anything to tell if they are compatible.
Also, this is for the IE Lab. I only have acess to CUCX 5.0. How much does it differ from CUCX 7? Wondering if I will be able to improvise for my studies.
Whereas they are differnt in some capacity, they are very similar.
Here is a compatibility matrix so you can also chek the compatibility of you UCCX application with the CUCM application.
6.x - 8.x Matrix
