Migration for Highly Customized Odoo Systems Without Downtime
Upgrade heavily customized Odoo systems to 18 or 19 without stopping operations.
See How We Build for Complex BusinessesHighly customized Odoo systems power critical business operations across sales, finance, manufacturing, logistics, and integrations. Migrating these environments to newer Odoo versions is risky when custom modules, patched workflows, and live transactions are involved. A zero-downtime migration strategy ensures your business keeps running while code, data, and integrations are safely transitioned to Odoo 18 or 19.
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:
Enterprises with heavily customized Odoo systems
Businesses running mission-critical Odoo operations
Organizations upgrading from Odoo v12 to v17
Teams requiring uninterrupted ERP availability
This may not fit for:
Standard Odoo setups with minimal customization
Small databases with low transaction volume
Non-production or test-only environments
Teams comfortable with planned downtime
the real problem
Odoo migrations fail when customization complexity is underestimated.
Businesses running deeply customized Odoo systems face broken modules, incompatible ORM and API changes, data integrity risks, and integration failures during upgrades. Any downtime impacts sales, accounting, and operational continuity. Traditional migration approaches require system shutdowns, making them unsuitable for high-volume, always-on businesses. The challenge is migrating safely while transactions continue in real time.
how this is usually solved
(and why it breaks)
common approaches
In-place upgrades with system shutdown
Partial refactoring of custom modules
One-time data migration without live sync
Limited testing before go-live
Where these approaches fall short
Unexpected downtime and business disruption
Broken custom workflows after migration
Data inconsistency and reconciliation issues
High rollback risk
