What we migrate ## What Do Odoo Migration Services Include? Odoo migration services **move your data, settings and custom code safely to where they need to be**. Most projects are one of these six types. Data ### From spreadsheets and accounting software Customers, suppliers, products, open invoices and opening balances moved from spreadsheets or accounting packages into Odoo, cleaned and reconciled. ERP ### From another ERP system Master data, open transactions and the history you choose, moved from an older ERP when you start on Odoo. See [Odoo implementation services](https://ozonlayer.com/odoo-implementation-services/). Upgrade ### Odoo version upgrades Your Odoo database moved to a newer version, up to Odoo 20, with a test upgrade first and the production upgrade on a planned date. Code ### Custom module upgrades Custom and third-party modules ported to the target version, so the database can be upgraded. See [Odoo development services](https://ozonlayer.com/odoo-development-services/). Edition ### Community to Enterprise A move from Odoo Community to Odoo Enterprise, planned alongside any version upgrade and checked against your custom modules and data. Hosting ### Hosting changes A move between Odoo Online, Odoo.sh and your own servers, for example when you need custom modules that Odoo Online does not allow. How we work ## How Does an Odoo Migration Project Work? Every migration follows six steps, so **your live system changes only after a full rehearsal has been checked and approved**. Large or complex migrations are rehearsed more than once, and the final cut-over is planned around your quietest trading period. [Odoo consulting services →](https://ozonlayer.com/odoo-consulting-services/) ![Six-step Odoo migration process: assess source and scope, plan the cut-over, clean and map data, trial migration, reconcile and test, cut-over and go live](https://ozonlayer.com/wp-content/uploads/2026/10/odoo-migration-process-6-steps.webp) 01 ### Assess source and scope We review the current system, data quality, Odoo version and edition, custom modules and integrations. 02 ### Plan the cut-over We agree what moves (master data, open transactions, balances and history), the cut-over date and the plan, and you receive a written estimate. 03 ### Clean and map data Duplicates and obsolete records are removed, and every field is mapped to its place in Odoo. 04 ### Trial migration Data is loaded, or the database upgraded, on a test copy first, together with upgraded custom modules. 05 ### Reconcile and test Trial balance, stock, receivables and payables are reconciled, and your key users test their daily work. 06 ### Cut-over and go live The final load or production upgrade runs on the agreed date, followed by support through [Odoo support](https://ozonlayer.com/odoo-support-services/). What moves ## What Data Moves When You Migrate to Odoo? **Move what you need to run the business from day one**, and decide how much history is worth bringing. We agree the scope with your finance and operations teams before any data is extracted. ![How data moves to Odoo: from spreadsheets, an accounting package or an older ERP, through extract, clean and map, and load on a test database, to a reconciled trial balance, stock and receivables in Odoo](https://ozonlayer.com/wp-content/uploads/2026/10/odoo-data-migration-flow.webp) ### Master data Customers, suppliers, products, prices, the chart of accounts and taxes, cleaned before they are loaded. ### Open transactions Unpaid invoices and bills, open sales and purchase orders, and work in progress at the cut-over date. ### Opening balances The trial balance, stock quantities and values, and bank balances, reconciled with your old system. ### History Past transactions in full or in summary, depending on reporting needs and how clean the old data is. ### Documents Attachments such as contracts, product images and scanned documents, where they need to stay with the record. ### Users and access Users, roles and access rights set up for each team, so everyone sees what they need on day one. Latest release ## Upgrading to Odoo 20: What Should You Check? Odoo 20 was released in September 2026. **Before an upgrade, check your support window, your custom modules and the Odoo 20 changes that affect them.** From the official upgrade documentation and release notes: - **Support window:** each major version is supported for three years. On Odoo Online, a major-version upgrade is mandatory every two years; on Odoo.sh you have two more years after support ends; on your own servers you can stay on a version, although it is not recommended; - **Custom modules:** a database with custom modules cannot be upgraded until those modules are available for the target version; - **Access rights:** record rules are removed in Odoo 20 and a domain is set on each access right, so custom security needs reviewing; - **Integrations:** the XML-RPC and JSON-RPC API is deprecated, and its database service was removed in Odoo 20; - **Changed features:** field service is now part of Planning, and mail tracking values are replaced by tracking messages generated on the fly.

The steps follow the official Odoo upgrade documentation; the checks come from the Odoo 20 release notes. Upgrade service ## What Does Odoo’s Upgrade Service Cover, and What Does a Partner Add? With Odoo Enterprise, upgrading to the latest version is included. **Some of the work around it is not, according to Odoo’s own service-level agreement.** ![Comparison of Odoo's upgrade service included with Odoo Enterprise (standard apps and data, Studio customizations, code under a maintenance subscription) and what a partner handles (custom and third-party modules, cleaning data and configuration, training on the new version)](https://ozonlayer.com/wp-content/uploads/2026/10/odoo-upgrade-service-scope-partner.webp) Included ### Standard apps and Studio Odoo upgrades standard applications, Studio customizations while Studio and its subscription are active, and code under a maintenance subscription. Not included ### Custom modules Modules built in-house or by third parties, including Odoo partners, must be upgraded separately before the database can move. Not included ### Data and configuration clean-up Cleaning existing data and settings is outside Odoo’s upgrade service, so it is planned as part of the project. Not included ### Training Training users on the new version’s features and workflows is not part of the upgrade service. Before you start ## How Should You Prepare for an Odoo Migration? Good preparation **shortens the migration and lowers the risk at cut-over**. Moving from another system to Odoo? Our implementation team plans the configuration and the data migration together. [Odoo implementation services →](https://ozonlayer.com/odoo-implementation-services/) 01 ### List what you have Note your current system or Odoo version, edition, hosting, custom modules and integrations. 02 ### Clean your data Remove duplicate and obsolete customers, suppliers and products before the first extract. 03 ### Decide how much history Agree with finance which years must move in full and which can move as balances. 04 ### Choose the cut-over date Pick a date away from month-end, year-end and your busiest trading periods. 05 ### Name testers Choose key users who will check balances and test daily work on the trial migration. Timeline and cost ## How Much Does Odoo Migration Cost? **It depends on scope.** Upgrading a standard database with few changes is usually a short project; migrations with many custom modules, integrations or years of history from another system take longer and are rehearsed more than once. ### What affects cost and timeline - the source system and the quality of its data; - the volume of records and how much history moves; - the number of custom modules and integrations; - the gap between your current and target Odoo versions; - edition and hosting changes; - the testing and training needed. With Odoo Enterprise, Odoo’s own upgrade of standard apps is included in the subscription; custom modules, data clean-up and training are quoted separately. [Request a migration estimate →](https://ozonlayer.com/contact-us/) ### Typical migration sizes These examples are indicative; your estimate confirms scope after the assessment: - **Standard upgrade:** a database with standard apps and Studio changes moved to a newer version; - **Upgrade with custom code:** custom modules and integrations upgraded and tested alongside the database; - **Migration to Odoo:** data moved from spreadsheets, an accounting package or another ERP as part of an implementation. You receive a written estimate before any work starts. Case studies ## Businesses We Have Moved onto Odoo Examples from different industries.

Our team replies to every enquiry with a straight answer on scope, timeline and budget. [Ask a migration expert](https://ozonlayer.com/contact-us/) **What are Odoo migration services?** Odoo migration services move a business onto Odoo, or onto a newer version of Odoo, without losing data. They cover data migration from spreadsheets, accounting packages and other ERP systems, Odoo version upgrades, custom module upgrades, and moves between editions or hosting types. **What is the difference between an Odoo upgrade and a migration to Odoo?** An upgrade moves an existing Odoo database to a newer Odoo version. A migration to Odoo moves data from another system, such as spreadsheets or a different ERP, into a new Odoo database. Odoo's upgrade documentation notes that its upgrade service does not cover migrating from another ERP. **How do I upgrade to Odoo 20?** Request an upgraded test database, upgrade any custom modules to Odoo 20 at the same time, and test every process on the copy. When all issues are fixed, plan and run the production upgrade. OzonLayer manages these steps and the custom module work. **Is upgrading Odoo free?** With Odoo Enterprise, upgrading to the latest version is included for standard apps, Studio customizations while Studio is active, and code under a maintenance subscription. Odoo's service-level agreement excludes custom modules built in-house or by partners, data and configuration clean-up, and training. **Is an Odoo upgrade mandatory?** Each major version is supported for three years. On Odoo Online, a major-version upgrade is mandatory every two years and minor versions are upgraded a few weeks after the next release. On Odoo.sh there are two more years to upgrade after support ends, and on your own servers you can stay on a version, although Odoo does not recommend it. **What data can be migrated to Odoo from another system?** Usually master data such as customers, suppliers, products and the chart of accounts, open transactions such as unpaid invoices and open orders, opening balances for accounts and stock, and the history you choose. The scope is agreed with your finance and operations teams first. **What happens to custom modules during an upgrade?** A database with custom modules cannot be upgraded until those modules are available for the target version. Their code is ported and tested in parallel with the upgraded test database, including changes such as the new access rights in Odoo 20. **Can you move us from Odoo Community to Odoo Enterprise?** Yes. Changing edition is a separate step from a version upgrade, so it is planned together with any upgrade and checked against your custom modules and data. **How long does an Odoo migration take?** It depends on the version gap, the number of custom modules and integrations, data volume and how much history moves. A standard upgrade is usually short, while a migration from another ERP is part of a larger project. We confirm the timeline in the estimate. **How much does Odoo migration cost?** Cost depends on the source system and data quality, the volume and history to move, custom modules, integrations, edition or hosting changes, and testing and training. You receive a written estimate after the assessment. **Will there be downtime during the migration?** During a production upgrade, the database is unavailable for the time the upgrade takes, according to Odoo's documentation. For migrations from another system, the old system is frozen for the final load. Both are scheduled outside your busiest periods.
