Tom,
I'm glad I found this thread. I just did a rather (I thought)
straight-forward reconfigure of my database. I had the ancient wview
schema, and I wanted to update to the wview_extended, since I installed
Rich's MQTTSubscribe to get co2, pm2.5 and pm10 values from my Qingping Air
Monitor Lite. Anyway, I got the following error:
weectl database reconfigure
Using configuration file */etc/weewx/weewx.conf*
Copying database 'weewx.sdb' to 'weewx.sdb_new'
The new database will use the same unit system as the old ('US').
Are you sure you wish to proceed (y/n)? y

All I did was change the schema in my weewx.conf from
schema = schemas.wview.schema
to
schema = weewx.schemas.wview_extended.schema
I dropped in your new manager.py and it worked.
