migrating client PCs from Proxy Server 2.0 to ISA Server

[wallst32]

I have a small environment that has been using Proxy Server 2.0 on NT4. They are upgrading to W2K3 Servers and ISA Server.

The NT4/Proxy Server machine will be replaced with new hardware. The new hardware will have W2K3 and ISA server installed and will take the IP address of the old system.

Client PCs have the Proxy client installed and full internet access (no restrictions on outbound traffic). What needs to be done on the client PCs after the new ISA server is in place? Install the ISA firewall client, uninstall the old Proxy client, nothing at all?

TIA

The old Proxy client will allow the clients to browse the internet as long as the ISA server allows them. You can then update the Proxy client software to the Firwall client software at will.
