Hi,
In Odoo, you cannot delete a website directly if other records depend on it, because the website is linked to models like pricelists, menus, and pages through foreign keys. That’s why you see the validation error about the pricelist requiring the website. The cleanest approach is usually to archive the old website instead of deleting it. Every website record has an active field, so when you archive it (set active=False), the website is hidden but all dependencies remain safe. You can do this by enabling Developer Mode, opening the old website from Website → Configuration → Websites, and choosing the Archive option from the action menu. If you really want to delete the website, you must first reassign or clear all dependencies—for example, open Website → Configuration → Pricelists, and either remove the old website reference or point them to your new website. Once nothing references the website, deletion is possible. A third, more technical option is a hard delete by running SQL to clear all foreign key references and then remove the website record, but this is not recommended outside of a test database because it can break your system. Since you mentioned you’re just starting and not transacting yet, the simplest and safest option is to either archive the old website or create a fresh database with only the website you want. This gives you a clean slate and avoids the risk of breaking dependencies.
Hope it helps
