+## Post-Migration Validation
+
+After migration, use the validation script to check for broken views and XPath errors.
+
+### Quick Start
+
+```bash
+./scripts/validate_migration.sh ou17 odoo17
+```
+
+### What Gets Validated
+
+Runs in Odoo shell, no HTTP server needed:
+
+| Check | Description |
+|-------|-------------|
+| **Inherited views** | Verifies all inherited views can combine with their parent |
+| **XPath targets** | Ensures XPath expressions find their targets in parent views |
+| **QWeb templates** | Validates QWeb templates are syntactically correct |
+| **Field references** | Checks that field references point to existing model fields |
+| **Odoo native** | Runs Odoo's built-in `_validate_custom_views()` |
+
+### Running Directly
+
+You can also run the Python script directly in Odoo shell:
+
+```bash
+compose run odoo17 shell -d ou17 --no-http --stop-after-init < lib/python/validate_views.py
+```
+
+### Output
+
+- **Colored terminal output** with `[OK]`, `[ERROR]`, `[WARN]` indicators
+- **JSON report** written to `/tmp/validation_views_<db>_<timestamp>.json`
+- **Exit code**: `0` = success, `1` = errors found

+Post-Migration View Validation Script for Odoo
+
+Validates all views after migration to detect:
+- Broken XPath expressions in inherited views
+- Views that fail to combine with their parent
+- Invalid QWeb templates
+- Missing asset files
+- Field references to non-existent fields
+
+Usage:
+    odoo-bin shell -d <database> < validate_views.py

+    # Or with compose:

+Exit codes:
+    0 - All validations passed
+    1 - Validation errors found (see report)

+
+Post-migration view validation for Odoo databases.
+
+Validates:
+    - Inherited view combination (parent + child)
+    - XPath expressions find their targets
+    - QWeb template syntax
+    - Field references point to existing fields
+    - Odoo native view validation
+
+Arguments:
+    db_name         Name of the database to validate
+    service_name    Docker compose service name (e.g., odoo17, ou17)
+
+Examples:
+    $0 ou17 odoo17
+    $0 elabore_migrated odoo18
+
+Notes:
+    - Runs via Odoo shell (no HTTP server needed)
+    - Report is written to /tmp/validation_views_<db>_<timestamp>.json
