I would like to know if the 'update' process for the Winsock Proxy Client will actually update the client from Winsock Proxy 2.0 to Firewall client for ISA? I am planning a migration from my current Proxy Server 2.0 to ISA in the near future. I have seen the comment that the Winsock Proxy Client will continue to work with ISA after updating your Proxy Server, but I want to find out if I will need to manually update the clients from Winsock Proxy to Firewall. If so, does this involve an uninstall of the Winsock Proxy and then an install of the Firewall client?
