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?
