change the explicit proxy from one vdom to another

Hi folks,

i have a question:

I want to move my explicit proxy to another vdom because we upgraded our Internet connection so we don't need the DSL (which is actually on a vdom just for surfing) , which is used by the clients to surf the internet and move to the 100 MBit FTH Connection.

Is there a problem to make 2 explicit Proxys on each vdom and move the clients to the new one by group policy if everything is fine ?

Is it also possible to use our FSSO Agent with 2 different vdoms, which means 2 different ip's ?

Thanks for helping
