Every Odoo version. One expert team.
From OpenERP 7.0 to Odoo 20.0, NexGen has engineered, customized, and upgraded databases across the full platform history — with zero data loss.
We upgrade any release on this path — including heavily customized databases.
Zero data loss
Trial migrations, financial reconciliation, and validated cutovers protect every ledger and stock move.
Custom code ported
Legacy Python and JS modules are refactored to modern ORM and OWL standards — upgrade-safe.
Modern performance
Move to faster PostgreSQL, cleaner UI, stronger security, and native AI-ready Odoo 20 features.
