implementing CalDAV and CardDAV would enable exchanging contacts and activities/calendars with many external systems, e.g., Google calendar, MS Exchange...
This is something we're interested in implementing but it's very complex development so we currently don't have a timeline for when it will be developed.
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...
