Hi,

In Odoo.sh, your custom code and your database content are two completely separate things,  so just importing a SQL/DB dump will not bring over your custom modules, models, views, or controllers.

DB Dump contains,

      - All data stored in the database (products, partners, sales orders, settings, etc.).

      - Configuration records, including some settings for installed apps.

      - But it does NOT include the actual Python/JS/XML code of your custom modules.

Migration steps,

1- Clone the branch from the old Odoo.sh repo to your local machine.

2- Push that branch to the new Odoo.sh project’s GitHub repository.

3- On the new Odoo.sh, deploy that branch.

4-Once it’s running, restore the database using the SQL dump from the old Odoo.sh.

Hope it helps
