If you search in source code for "RecordBegin(RcVc" you will see all the fields that you can use. The "flags" go from 1 to 29 so anything higher than flags[29] will not work.
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...
