IT Management Suite 7.1 SP2 MP1.1

I am still running 7.1, I upgrade all my workstaion from 7.0 to 7.1 last year in May, the other day I was talk to Altiris technical support, and he suggested me to upgrade to IT Management Suite 7.1 SP2 MP1.1.

and I read some of Release Notes, the only thing that I concern about it...

Did this will break the security permission setting?

Did the inventory forwarding will be still working? I have another Altiris server they are forwarding their inventory to me.

Did all the policy setting will still work?

What will I be worry about this?

Thanks

Lillian
