Thanks Dejan. When I asked this question, data security plans did not exist. It seems that "background backup" was accidentally added and set by default in 8.1, but it has reverted back to normal behaviour in versions since then.
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...
