Hello,
i had an old database with view data until 2013.
From 2018 i started to use weewx without import old data.
Today i found an old backup and tried merge both db using this:
$ sqlite3 wview.sdb
sqlite> .output wview.dump
sqlite> .dump
sqlite> .quit
Then import the dumped data into the weewx database:
$sqlite3 weewx.sdb
sqlite> .read wview.dump
(this will emit an error "table archive already exists", but then should proceed to import the wview data)
sqlite> .quit
Starting weewx created al NOAA from 2013, but all data are empty until 2018.
There is a solution? is better restore a clean db from 2018 and forget old data?
Thanks in advance!
