Can we edit the Virtual server properties using "LocalLB::VirtualServer::create"

Dear Experts,

I came across in the F5 devcentral as LocalLB::VirtualServer::create will be used to create/update the virtual server. But when i try to call the same API again with different input, I am getting the error as below.

"The requested Virtual Server (/Common/New112) already exists in partition Common."

Can we edit the virtual server properties using the same create call? Since its not working, can anybody help me to edit the exiting virtual server properties. Note: I can achieve this through setting each and every prameters like setProtocol, setDestinationAddress. But i am expecting like a single Create call like would really help me.
