Why You Must Upgrade from Odoo 8 to Odoo 18
Odoo 8, released in 2014, is now end-of-life—lacking security patches, performance optimizations, and compatibility with modern infrastructure. Businesses still running Odoo 8 face:
• ❌ Outdated Python 2 codebase
• ❌ Insecure and deprecated modules
• ❌ Poor performance on modern servers
• ❌ Limited support for cloud-native deployment
Upgrading to Odoo 18 Community Edition unlocks:
• ✅ Python 3.10+ compatibility
• ✅ Lightning-fast UI and backend performance
• ✅ Modular scalability and RESTful APIs
• ✅ Enhanced security and compliance
• ✅ Seamless integration with AWS, Azure, GCP
At InfraNext, we specialize in end-to-end Odoo migration services—from legacy code refactoring to full-stack deployment.
Step-by-Step Migration Blueprint
📁 Step 1: Audit Your Existing Odoo 8 Environment
Before touching a single line of code, we perform a deep technical audit:
• Inventory all installed modules (core + custom)
• Identify deprecated models, views, and controllers
• Map third-party integrations and external dependencies
• Analyze database schema and field usage
• Document business-critical workflows and automation
🔍 Pro Tip: Use ir.module.module and ir.model.fields to extract module and field metadata.
Step 2: Set Up Odoo 18 Development Environment
We provision a containerized dev environment using Docker or Ansible:
• Install Odoo 18 from source
• Configure PostgreSQL 14+
• Set up Python 3.10 virtualenv
• Enable developer mode and logging
• Integrate Git for version control and CI/CD pipelines
💡 Bonus: We deploy staging environments on AWS EC2 or Azure VMs for isolated testing.
Step 3: Refactor Custom Modules
Odoo 8 modules use legacy ORM and Python 2 syntax. We refactor:
• osv.osv → models.Model
• fields.function → @api.depends
• Legacy XML views → QWeb templates
• JS assets → Owl framework (if applicable)
We also rewrite:
• Controllers (http.Controller)
• Security rules (ir.model.access.csv)
• Menu items and actions (ir.actions.*)
🔧 Tooling: We use 2to3, black, and custom linters to automate syntax upgrades.
Step 4: Migrate Database Schema and Records
We build custom migration scripts to:
• Export data from Odoo 8 using XMLRPC or direct SQL
• Transform schema to match Odoo 18 models
• Import data using ORM or CSV loaders
• Validate relational integrity and constraints
📊 Examples:
• account.invoice → account.move
• res.partner.category → res.partner.tag
• sale.order.line fields remapped for new tax logic
Step 5: Test, Validate, and Harden
We run automated and manual tests to ensure:
• ✅ Functional parity with legacy workflows
• ✅ UI/UX consistency across modules
• ✅ Performance benchmarks under load
• ✅ Security compliance and access control
• ✅ Integration with external APIs (e.g., payment gateways, CRMs)
🧬 CI/CD: We use Jenkins or GitHub Actions to automate test pipelines and rollback logic.
Step 6: Deploy to Production
Once validated, we deploy to production using:
• 🔐 Hardened Linux servers (Ubuntu 22.04 LTS)
• 🔄 Nginx reverse proxy with SSL
• 🧱 PostgreSQL with WAL archiving
• 📦 Docker or systemd-managed services
• 📈 Monitoring via Prometheus + Grafana
We also set up:
• 🔁 Daily backups with retention policies
• 📣 Notification hooks for errors and updates
• 🧩 Future-proofing for Odoo 19+ compatibility
