Odoo Migration & Upgrade

Whether you are moving from an old Odoo version to the latest one, or switching your business from a legacy ERP to Odoo, migration is the moment when your data, processes and customizations must arrive intact on the other side. NextERP has been doing this since 2018, with a focus on Romanian localization and on the custom modules that usually make a migration harder.

What we migrate

Odoo version upgrades — from Odoo 12, 14, 16 or 17 to the current version, adapting custom modules to the new API and preserving the Romanian localization (chart of accounts, VAT, e-Factura, SAF-T).
Migration from another ERP — SAGA, WinMentor, SAP, Microsoft Dynamics or in-house systems: we bring over master data, balances, partners, stock and the relevant history.
Database consolidation — multiple companies or instances brought into a single Odoo platform.

Our migration process

Audit — we inventory the source version, installed modules, customizations and data volume.
Test environment — we build a test instance and run the migration there, without touching production.
Data migration — we transfer data with verifiable, reproducible scripts, not by hand.
Code adaptation — we rewrite custom modules for the new version and revalidate the Romanian localization.
Validation — we check accounting balances, stock and tax reports together before go-live.
Go-live — we bring the new version online with minimal downtime and dedicated support right after.

Why the right partner matters

An Odoo migration most often fails on two things: custom modules that were not correctly adapted to the new version, and the Romanian localization (ANAF filings, e-Factura, SAF-T) that must work from day one. NextERP is an OCA contributor and a developer of RO localization modules — we know exactly where the problems appear and how to solve them.
