You can put your files where ever you want, just tell elogd where to find the elogd.cfg file via the "-c" flag. Then tell elogd where to find files in the elogd.cfg file via the "Logbook dir" and "Resource dir" directives.
On the new server in the logbook that should have several 2020 entries it stops on the last entry of 2019.
On the old server after stopping elogd i get:
/usr/sbin/elogd -v 3
Cannot open "elogd.cfg": No such file or directory
Are the files supposed to be in /usr/local/elog or /usr/share/elog? I have both on the old server. I only synced /usr/local/elog to the new server. In any case the Logbook with 2020 entries does not show a 2020 directory.
My backup system also does not show any 2020 logbook directories. It was current up to this week when I started this process.
