How to Upgrade SMP Management Agent in SSR 2013

We are running with Symantec System Recovery Management Solution 2013 which is running on top of SMP 7.1 SP2 MP1.

My question is, how can I upgrade the version of SMP 7.1 to the latest rollup so that the management agent deployed to the client includes the latest version.

I've looked under the Symantec Installation Manager tool but the only update it lists is the SMP 7.5 which I am sure will not work with SSR 2013.
