I use a Pi4 without a fan and Debian Buster as my operating system. Installed is
Weewx-Multi ( vers. 4.7 Season and Belchertown skin for both instances: Davis / Ecowitt ) with a MySQl database. The CPU temperature reached almost 80° and the Raspberry started to have problems. On 27 February, I switched the database to Sqlite without importing the existing MySQl data and the CPU temperature was then at 60°C.
Yesterday I did a transfer of all MySQl databases with "wee_database --config=/etc/weewx/xyz.conf --transfer --dest-binding=dest_binding" and a "rebuild-daily" . It worked without errors and all records ( table archive I have checked ) are present.
Unfortunately 2 problems occur:
1. the entries up to 28 February are missing from the February NOAA table and the months January and February are missing from the year table.

2. the annual graphs are also only created with the data from the end of February (I deleted all annual images once).

This is the case for both instances.
The NOAA report behaves identically with the Belchertown skin. Only the yearly graphic is complete, in contrast to the season skin.
As an attachment, here is the syslog with debug = 0 and debug = 1.
