This command dumps the contents of your database in JSON format and saves it to a file named "data.json"
python manage.py dumpdata > data.json
Note: For excluding any models use "--exclude"
python manage.py dumpdata --exclude auth.permission --exclude contenttypes > data.json
Add the new database to your settings.py file like this and run all your migrations for creating the table structure and DB schema.
python manage.py migrate --database=new
After migrations
Your data.json is of UTF-16LE and you need to convert it into UTF-8 and than load your data to new database.
python manage.py loaddata data.json --database=new
This process is useful for creating backups, migrating data between databases, or sharing sample data with others working on the project. Keep in mind that the **dumpdata** and **loaddata** commands are part of Django's serialization framework, and they work with various serialization formats, not just JSON.
