Claim:
1. A system for transferring information from a first PI server on a source platform computer coupled to a first network to a second PI server on a destination platform computer coupled to a separate second network, comprising: a send platform computer coupled to the first network and in communication with the first PI server; a receive platform computer coupled to the second network and in communication with the second PI server; and a one-way data link coupling the send platform computer to the receive platform computer, the one-way data link configured to transfer data only from the send platform computer to the receive platform computer and to prevent any signal from passing from the receive platform computer to the send platform computer; wherein the first PI server includes historical information and transfer configuration information, wherein the send platform computer is configured to continually receive a predefined portion of the historical information according to preset parameters from the first PI server and transfer the predefined portion of the historical information to the receive platform computer via the one-way data link, wherein the send platform computer is also configured to read the transfer configuration information from the first PI server and modify the preset parameters based on any change indicated therein without stopping the transfer, wherein the receive platform computer is configured to receive the predefined portion of the historical information from the send platform computer via the one-way data link, to query the second PI server to determine if a corresponding portion of the historical data exists on the second PI server, and if a corresponding portion of the historical data does not exist on the second PI server, to transfer the current portion of the historical information to the secondary PI server, and wherein the receive platform computer is coupled to the send platform computer only via the one-way data link.
