As a general advice, I would suggest you to move to 8.0.x code for WLC perspective (as long as you got AP model that support 8.0). Current code you are running already deferred, so TAC would suggest to upgrade it if you log a case for it.
Prime, go for 3.1 as version you are running is bit old.
MSE, go with 8.0.x
