Hi Paul! The file is not touched but the communication channel is encrypted. All communications between SERP and SERP server are encrypted + we use additionally TLS 1.2 protocol. Hope this helps to answer your question.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
