Paperless-ngx import script not working

[osswaldo]

Hello,
I have an existing paperless-ngx installation running with docker-compose on my old Raspberry Pi. Now I want to move it to my Proxmox server. I made a backup of my existing paperless-ngx data using "docker compose exec -T webserver document_exporter ../export" and copied the backup to new paperless-ngx lxs (installed using the default installer script bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/paperless-ngx.sh)").
Now I want to import the old data. I tried python3 /opt/paperless/src/documents/management/commands/document_importer.py /root/backup/, but it doesn't work:

Traceback (most recent call last):

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

How can I import the old data?

Thanks a lot!

Did you figure this out? I'm in the same boat.

Here the same..

Unfortunately not. I installed it from scratch using the docker method. If you copy all the data and adjust the paths in the docker configuration file, it worked fine.

There’s another post from tteck on here. I’m on mobile and cannot give it exactly, but it looks like

cd /opt/paperless/src
python3 manage.py document _importer /path/to/export

that worked for me.
