Hi, you can't directly restore an Odoo 15 DB to Odoo 17 because of structural changes. You need to migrate step-by-step (15 → ​​16 → 17) using OCA OpenUpgrade scripts . Simple data (like customers/products) can be exported/imported via CSV, but for full DB migration, scripts are required. 

Hello Jeffry,

For the Odoo community edition, Odoo does not upgrade tool like it has for the enterprise edition. To Migrate data from the Odoo 15 CE to Odoo V17 CE, first, you need to decide what type of data you want to migrate. If you want to migrate static data like customers, products, categories and attributes then this can be achieved with the help of a custom Python script.

If you want to migrate dynamic data like sales orders, invoices, reports etc then you will have to migrate the complete database. For this, there are some OCA scripts which can be used for the migration of the community edition. In this case, you will have to first migrate your Odoo v15 to Odoo v16 and then Odoo v16 to Odoo v17.
Simply restoring the Odoo v15 database into Odoo v17 will not work due to the different technical structures of both versions.

If you need any assistance in Odoo migration, you can contact us at support@webkul.com as we provide the Odoo migration services including the cross-platform Odoo migration which you can check here >> https://webkul.com/odoo-migration-services/

Hello, the easiest way to transfer your records to a new database is by exporting them in CSV or XLS format and then re-importing them into the new database.

You can do this by following these steps:

1. Export the Records: Go to the list view of the desired records, select them, and export them in a compatible format (CSV or XLS). Be sure to include all the required fields.
2. Prepare the File: Ensure that the exported file includes all necessary fields for the new database, especially if there are mandatory fields that need to be filled.
3. Import into New Database: In the new database, navigate to the import section and upload the exported file. Odoo will map the columns to the correct fields automatically, but make sure to review the mapping and correct any discrepancies.
4. Repeat for Other Objects: If you're migrating multiple objects (like customers, products, etc.), repeat the export-import process for each one.

This method is straightforward and ensures that the data is correctly imported into the new database.

Hi,

Direct restoring a odoo 15 to odoo 17 database is not possible. because there is a so many changes in the fields and functionalities coming from odoo 15 to 17.so it is required to do complete odoo database migration from odoo 15 to 17.

Hope it helps
