Odoo Upgrade Advisor

Overview

Upgrading Odoo between major versions (e.g., v15 → v16 → v17) requires careful preparation, testing, and validation. This skill provides a structured pre-upgrade checklist, guides you through the upgrade tools (Odoo Upgrade Service and OpenUpgrade), and gives you a post-upgrade validation protocol.

When to Use This Skill

• Planning a major Odoo version upgrade.
• Identifying which custom modules need to be migrated.
• Running the upgrade on a staging environment before production.
• Validating the system after an upgrade.

How It Works

1. Activate: Mention @odoo-upgrade-advisor, state your current and target version.
2. Plan: Receive the full upgrade roadmap and risk assessment.
3. Execute: Get a step-by-step upgrade command sequence.

Upgrade Paths

From	To	Supported?	Tool
v16	v17	✅ Direct	Odoo Upgrade Service / OpenUpgrade
v15	v16	✅ Direct	Odoo Upgrade Service / OpenUpgrade
v14	v15	✅ Direct	Odoo Upgrade Service / OpenUpgrade
v14	v17	⚠️ Multi-hop	v14→v15→v16→v17 (cannot skip)
v13 or older	any	❌ Not supported	Manual migration required

Examples

Example 1: Pre-Upgrade Checklist

BEFORE YOU START:
  ☑ 1. List all installed modules (Settings → Technical → Modules)
        Export to CSV and review for custom/OCA modules
  ☑ 2. Check OCA compatibility matrix for each community module
        https://github.com/OCA/maintainer-tools/wiki/Migration-Status
  ☑ 3. Take a full backup (database + filestore) — your restore point
  ☑ 4. Clone production to a staging environment
  ☑ 5. Run the Odoo Upgrade pre-analysis:
        https://upgrade.odoo.com/ → Upload DB → Review breaking changes report
  ☑ 6. Review custom modules against migration notes
        (use @odoo-migration-helper for per-module analysis)
  ☑ 7. Upgrade and test in staging → Fix all errors → Re-test
  ☑ 8. Schedule a production maintenance window
  ☑ 9. Notify users of scheduled downtime
  ☑ 10. Perform production upgrade → Validate → Go/No-Go decision

Example 2: Community Upgrade with OpenUpgrade

# Clone OpenUpgrade for the TARGET version (e.g., upgrading to v17)
git clone https://github.com/OCA/OpenUpgrade.git \
  --branch 17.0 \
  --single-branch \
  /opt/openupgrade

# Run the migration against your staging database
python3 /opt/openupgrade/odoo-bin \
  --update all \
  --database odoo_staging \
  --config /etc/odoo/odoo.conf \
  --stop-after-init \
  --load openupgrade_framework

# Review the log for errors before touching production
tail -200 /var/log/odoo/odoo.log | grep -E "ERROR|WARNING|Traceback"

Example 3: Post-Upgrade Validation Checklist

After upgrading, validate these critical areas before going live:

Accounting:
  ☑ Trial Balance totals match the pre-upgrade snapshot
  ☑ Open invoices, bills, and payments are accessible
  ☑ Bank reconciliation can be performed on a test statement

Inventory:
  ☑ Stock valuation report matches pre-upgrade (run Inventory Valuation)
  ☑ Open Purchase Orders and Sale Orders are visible

HR / Payroll:
  ☑ All employee records are intact
  ☑ Payslips from the last 3 months are accessible and correct

Custom Modules:
  ☑ Every custom module loaded without ImportError or XML error
  ☑ Run the critical business workflows end-to-end:
      Create sale order → confirm → deliver → invoice → payment

Users & Security:
  ☑ User logins work correctly
  ☑ Access rights are preserved (spot-check 3-5 users)

Best Practices

• ✅ Do: Always upgrade on a copy of production (staging) first — never the live instance.
• ✅ Do: Keep the old version running until the new version is fully validated and signed off.
• ✅ Do: Check OCA's migration status page: OCA Migration Status
• ✅ Do: Use the Odoo Upgrade Service pre-analysis report to get a list of breaking changes before writing any code.
• ❌ Don't: Skip intermediate versions — Odoo requires sequential upgrades (v14→v15→v16→v17).
• ❌ Don't: Upgrade custom modules and Odoo core simultaneously — adapt Odoo core first, then fix custom modules.
• ❌ Don't: Run OpenUpgrade against production directly — always test on a staging copy first.

Limitations

• Covers v14–v17 only. Versions v13 and older have a fundamentally different module structure and require manual migration.
• Enterprise-exclusive module changes (e.g., sign, account_accountant) may have undocumented breaking changes not included in OpenUpgrade.
• The Odoo.sh automated upgrade path has a separate workflow (managed from the Odoo.sh dashboard) not covered here.
• OWL JavaScript component migration (legacy widget → OWL v16+) is a complex front-end topic beyond the scope of this skill.
