Odoo Services - Upgrade and Migration

# Migration to Odoo - Without Data Loss and Without Stress

Changing systems is postponed for years out of fear: "we'll lose the data", "work will stop". With a controlled process and a test migration before the final one - neither of the two happens. **We have moved customers from Excel, from accounting software, from other ERP systems and from old Odoo versions.**

## The Four Typical Starting Points

###### From Excel and Google Sheets

The most common case for small and medium-sized companies. **We structure the data, clean up duplicates, and import.** The chaos stays in the past.

###### From accounting software

Catalogs, chart of accounts, balances, counterparties. **The Bulgarian localization in Odoo handles VAT and the NRA from day one.**

###### From another ERP system

We analyze the structure, map the data to the Odoo model and **migrate in controlled cycles with tests.**

###### From an old version of Odoo

**We upgrade to the current version, including carrying over the customizations.** See also the upgrade included in the Annual subscription below.

Process

## A Controlled Process, Not a Leap into the Unknown

1

##### Data analysis

What you have, in what format, what is critical and what can be cleaned up.

2

##### Mapping

Fields from the old system are mapped to the Odoo structure, with clear transformation rules.

3

##### Test migration

A trial import in a test environment. Your team verifies the data, and discrepancies are corrected.

4

##### Final migration

Only after a successful test. If needed - a short period of parallel operation of the two systems.

## Odoo grows every year. So does your system.

Odoo releases a new major version every year - with new features, better performance and security support. The major upgrade moves your system to the new version so that existing functionality works as before - including the modules we developed.

[See the support packages](/en/odoo-erp/services/support.md)

*In the Annual support subscription, one major upgrade is included - without an extra budget.*

## Frequently Asked Questions

Will our work stop during the migration?

No. The old system keeps running until the new one has passed testing. The switchover itself is planned for a quiet period - a weekend or the end of the month.

What happens to the data that is not migrated?

Nothing is lost - the old system/archive stays with you for reference. We migrate what is active, and the archive keeps the history.

How much does a migration cost?

It depends on the volume and quality of the data. After the free assessment, you receive a fixed quote - no surprises midway.

Can we migrate in stages?

Yes, and it is often more sensible: first counterparties and balances, then history, then additional modules. The stages are defined in the Solution Design Document (SDD).

We use a very old version of Odoo with third-party customizations. Is that a problem?

It's not a problem, it's a routine task. We audit the customizations, and tell you which are worth carrying over and which are cheaper to replace with standard features.

## Your data is more portable than you think.
