Did the suggestion by Aldevinas work for you? If yes, then may I close this ticket? If it's still a problem, then maybe you could write a Wish and let us know the Wish title text, so I can follow up.
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...
