Odoo Report Migration

Use this skill for report-specific migration work. Compose it with odoo-migration for the module port, the source and target version skills for framework details, odoo-report-design for layout decisions, and odoo-web-testing when browser or asset behavior is involved.

First Move

Identify the source and target versions, module and report XML IDs, current rendering environment, report action, template chain, paper format, assets, custom value provider, and the visual requirements that must remain stable.

Workflow

1. Freeze a baseline. Render HTML and PDF using deterministic records and record the version, commit, language, company, user, paper format, and renderer details.
2. Inventory dependencies: inherited templates, external layouts, report assets, SCSS/CSS, fonts, images, paper formats, translations, and report actions.
3. Apply every intermediate Odoo migration checklist for a multi-version jump. Separate API/data migration from presentation changes.
4. Inspect the target version's upstream report templates, asset bundles, CSS framework, renderer, and report action fields before porting XPath or CSS.
5. Port the smallest compatible change. Prefer stable inherited anchors over copying the old core template.
6. Re-render the same fixture set and classify every difference as intended, renderer noise, or a regression.
7. Verify access, data semantics, translations, pagination, paper geometry, assets, and multi-record behavior before declaring success.

Guardrails

• Do not call a report visually preserved because it merely loads or produces a PDF.
• Do not compare PDF bytes as the primary visual assertion.
• Do not fix a layout regression with arbitrary CSS before checking target templates, asset bundles, paper format, fonts, and renderer behavior.
• Do not broaden report access or expose data while changing presentation.
• If the baseline cannot be rendered, record the missing evidence and use a clearly labeled reconstructed baseline instead of claiming equivalence.
