Sounds to me like copying data from Excel for Mac is inserting an extra carriage return/form feed character. What happens if you paste into TextEdit first, then copy from there and paste into the transaction?
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...
