Hello,

Restarting your database without losing your website and configuration is possible, but it's important to proceed with caution to avoid losing any important data.

Here are the general steps to restart your database while preserving your website and configuration:

1. Backup Your Data: Before making any changes, it's crucial to create a backup of your database to ensure you can restore it if anything goes wrong.

2. Export Website Data: If you have customizations or content on your website that you want to keep, export this data separately. You can export website pages, products, and other relevant information.

3. Export Configuration: Export any configurations you've made in Odoo, such as custom fields, workflows, or settings that you want to keep.

4. Restart Database: You can restart your database by reinstalling Odoo. During the installation process, you'll be prompted to create a new database. Make sure to choose a different database name than your current one to avoid overwriting it.

5. Import Data: After reinstalling Odoo, you can import your backed-up data, website content, and configurations into the new database.

6. Verify Data: Once the import is complete, verify that all your data, website content, and configurations are correctly restored.

It's essential to test your new database thoroughly before using it in a production environment to ensure everything is working as expected.

Hope it helps.
