I have been runnning weewx on a Raspberry Pi 4 in simulator mode for over a 
week gaining confidence in it's (and my) ability.  I am able to generate 
reports, transfer files to a web server and successfully imported a Davis 
WeatherLink (.wlk) file.  The next step is to cut-over to my actual weather 
station hardware and go "live".

My weather station hardware is an older Davis Weather Monitor II which will 
talk to the Pi over an RS-232 link via an RS-232 HAT.  The Weather Monitor II 
has the Davis data logger hardware which is capable of storing upwards of 1,500 
archive records.

My plan to migrate from Davis WeatherLink to weewx is as follows:

1. Delete the current weewx.sdb file, change drivers from simulator to Vantage, 
connect the weather station serial line and start weewx.  

2. After some number of archive data captures, stop weewx and let the Monitor 
II continue to store observation records to its internal data logger.

3.  Import historical data into the new weewx.sdb database.

4.  Restart weewx.

For this plan to work, the weewx driver needs to be smart enough to recognize 
and read multiple timestamped records from the station data logger (not just 
the current record).  Depending on the length of time the station is "offline" 
there could be tens or even hundreds of stored logger records.

Is the Vantage driver able to read multiple such saved logger records which 
weewx then loads into the database?  I have not seen it explicitly stated that 
the driver has the ability to retrieve multiple stored records from a logger.  
My migration plan depends upon this capability.

Thanks for any comments the group may offer.
