Dear community,
I try to import the database of my old weewx installation to the new system
(newly installed + new hardware) by exporting CSV file from the old
weewx.sdb and import with weectl import onto the new.
The process interrupts and I receive error messages as long as I have NULL
values in the CSV (NULL represented by comma separators without any value
",,"). When I remove the NULLs e.g. by "0" the process completes
successfully.
Does anybody have an idea, because I do not want to fill up the NULLs with
"0" because this is not accurate.
Thank you for support

Here ist the errorlog from weectl import:
Using database binding 'wx_binding', which is bound to database 'weewx.sdb'
Destination table 'archive' unit system is '0x01' (US).
Missing derived observations will be calculated.
All WeeWX UV fields will be set to None.
All WeeWX radiation fields will be set to None.
This is a dry run, imported data will not be saved to archive.
Starting dry run import ...
