What happened to the coupon module in Odoo 16?

The coupon, sale_coupon, and website_sale_coupon modules were replaced by a unified loyalty engine. The loyalty module handles coupons, promotions, gift cards, eWallets, and loyalty programs. Data migration scripts convert existing coupon programs to loyalty programs.

Is the Odoo 15 to 16 migration difficult?

It depends on your coupon/promotion usage. If you use standard coupons and promotions, Odoo's migration scripts handle most of the conversion. If you have custom coupon logic, it needs rewriting for the new loyalty architecture. Without coupon customizations, the migration is relatively smooth.

Do I need to migrate custom website themes?

The website builder UI changed significantly in v16. Custom themes may need updates for the new snippet system and editing experience. Test all custom pages, snippets, and themes in the new builder before going live.

Can the Knowledge app replace my wiki?

Possibly. The Knowledge app (Enterprise) provides article management, collaborative editing, templates, and embedded views. If your wiki needs are internal documentation and knowledge sharing, it can replace third-party solutions.

Odoo 15 to 16 Migration Guide: Loyalty Engine and Breaking Changes

Overview

The Odoo 15 to 16 migration centers on the unified loyalty/coupon engine replacement. If you use coupons, promotions, or loyalty programs, this migration requires significant attention. Otherwise, it is a relatively smooth upgrade with mostly additive changes.

Loyalty Engine Migration

The most impactful change: Odoo 16 replaces multiple coupon/promotion modules with a single unified loyalty engine.

Modules Replaced

coupon -> loyalty
sale_coupon -> sale_loyalty
website_sale_coupon -> website_sale_loyalty
pos_coupon -> pos_loyalty (enhanced)

Data Migration

Existing coupon programs, coupon codes, and active coupons need migration to the new loyalty model. The database structure is different — coupon programs become loyalty programs with different rule and reward structures. Odoo's migration scripts handle standard data, but custom coupon logic requires manual migration.

Custom Coupon Code

Any custom module that extends coupon.program, coupon.coupon, or related models needs rewriting for the new loyalty.program, loyalty.card, loyalty.rule, and loyalty.reward models.

New Features to Leverage

Knowledge App (Enterprise)

New article-based knowledge management system. If you used third-party wiki or knowledge base modules, consider migrating to the native Knowledge app.

Spreadsheet Dashboards

New spreadsheet and spreadsheet_dashboard modules in Community Edition. These may replace custom dashboard solutions or third-party reporting modules.

Data Recycle

New data_recycle module for automated data cleanup. Useful for organizations with data governance requirements.

Website Builder Changes

The website builder received a major UI overhaul with a new snippet system. Custom website themes and snippets may need adaptation for the new editing experience. Test all custom website elements thoroughly.

Other Changes

Dark mode support added — test custom CSS for dark mode compatibility
Onboarding framework (onboarding module) — can replace custom onboarding wizards
European e-invoicing (account_edi_ubl_cii) — check if it replaces custom e-invoicing

Migration Steps

Audit coupon/promotion customizations — this is the priority
Plan loyalty engine data migration for active programs and coupons
Review website theme compatibility with new builder
Check if Knowledge app replaces any third-party wiki modules
Test dark mode with custom CSS and themes
Validate spreadsheet modules against custom dashboard needs
