Odoo Migration From v12/v13/v14/v15/v16/v17 to Odoo 18/19
A structured, zero-data-loss migration from legacy Odoo versions to Odoo 18 or 19.
See How We Build for Complex BusinessesBusinesses running older Odoo versions face growing limitations around performance, security, compatibility, and maintainability. As Odoo evolves, staying on v12 to v17 makes systems harder to scale, riskier to maintain, and increasingly disconnected from new capabilities like improved UX, automation, and AI-driven features. Upgrading to Odoo 18 or 19 is not a simple version jump. It requires careful data mapping, code refactoring, dependency handling, and rigorous testing to avoid downtime or data loss.
Who This Is For
We usually work best with teams who know building software is more than just shipping code.
This is for teams who:
Businesses running Odoo v12 to v17
Companies with heavily customised Odoo systems
Teams facing performance or security issues
Organisations planning long-term ERP stability
This may not fit for:
Businesses already on the latest Odoo version
Systems without meaningful customisations or data
Teams looking for quick in-place upgrades
Short-term or experimental ERP deployments
the real problem
Odoo migrations fail when they are treated as upgrades instead of system rewrites.
Older Odoo installations often carry years of custom modules, workarounds, and legacy data structures. Direct upgrades break custom code, third-party integrations, and reporting logic. Businesses face slow systems, security gaps, and rising maintenance costs. Without a structured migration approach, teams risk data corruption, prolonged downtime, and unstable production environments. The challenge is not moving data, but preserving business logic while modernising the system.
how this is usually solved
(and why it breaks)
common approaches
Attempting direct upgrades without cleanup
Ignoring custom module compatibility
Migrating data without validation
Testing only after production deployment
Where these approaches fall short
Broken custom modules and workflows
Performance regressions after upgrade
Unexpected downtime during go-live
Long-term technical debt remains unresolved
