Hey Vince, thanks for the help !! I've got almost 3 years of archived weather data in my wview files, all of it in sql-lite3 databases and I'd like to pull it all into weewx (wth - in for a penny, in for a pound). My Davis Vantage Pro 2 wireless station is connected to computer via USB cable through Davis' datalogger-dongle. wview is currently doing 30sec sensor polling, 60sec data push intervals, and 5 min data archiving; html file creation for local browsing; and 5min FTP of html files to my ISP website for public viewing.
My uninformed plan before asking for advice was simply to: - stop weewx-sim - dump the simulated data files completely (essentially return weewx to its default install state) - as necessary, reconfigure weewx for location, station type, etc etc - stop wview live-polling and give it a few seconds to close files and clean house before shutting down - make sure the weewx interface is set to serial and device to /dev/ttyUSB0 - import wview data into weewx - start up weewx - as you say, monitor the crap out of the syslog entries weewx is already set up to run as a daemon (deb pkg install), so just rebooting the machine should tell me if I've covered all the bases or bolloxed it up. I was just concerned that there might be "undocumented" or "mis-documented" surprises in the wview->weewx import process. I'll be making backups of all the wview data files before doing any importing, as well as the default weewx files - so a mistake won't be totally terminal. But one small mess leads to another in linux, and before you know it a from-scratch-reinstall-of-image to SD card from Etcher starts to become appealing. Don't want to go there. Anything else I should considering before launching?
