Hello,
So far none has reported this behaviour which looks as a bug actually.
I haven't been able to repeat it on a test db, but if did instead, please report the bug attaching a sample data.
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...
