Migrating Data

System Message: ERROR/3 (<stdin>, line 4)

Unknown directive type "toctree".

   :caption: Migrating Data
   :hidden:

In the case that data needs to be migrated from one database installation to another, the following procedure can be used to export data, initialize the new database, and re-import the data.

Export Data

python3 InvenTree/manage.py dumpdata --exclude contenttypes --exclude auth.permission --indent 2 > data.json

This will export all data (including user information) to a json data file.

Initialize Database

Configure the new database using the normal processes (see Getting Started):

python3 InvenTree/manage.py makemigrations

python3 InvenTree/manage.py migrate --run-syncdb

Import Data

The new database should now be correctly initialized with the correct table structures requried to import the data.

python3 InvenTree/manage.py loaddata data.json

Important

If the character encoding of the data file does not exactly match the target database, the import operation may not succeed. In this case, some manual editing of the data file may be required.
