+## 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
+
