When a company decides to upgrade its Odoo system or move to a new version, it often thinks it's as simple as clicking a button. But the reality is very different. Data migration is like moving an entire company, files, furniture, papers, machines and even the coffee maker included… without losing a single screw.
Below we explain why this process takes time, is delicate and requires specialists. If you're thinking about migrating your Odoo system, this article will help you understand what to expect.
1. It's not copy and paste, it's precise reconstruction
Migrating data from one system to another isn't like copying a file from one folder to another. Every piece of data has to be reviewed, organized and validated so it works properly in the new system. Some rules change between Odoo versions, and not everything carries over automatically.
That's why it takes time to make sure nothing gets lost, that everything is clean and that it works as it should. If it's done wrong, reports can come out wrong, invoices can have errors and customers could disappear from the database.
2. Additional modules make everything more complicated
If your company has installed custom modules or modules bought from third parties (such as special reports, integrations or custom screens), each of those modules has to be adapted to the new version of Odoo. They aren't always compatible, and they often have to be reprogrammed from scratch.
This not only takes time, it can also cause errors if they aren't caught in time. That's why the more external modules you have, the more complex and slower the migration process will be.
3. The data has to be cleaned up and organized before it's moved
Before migrating, the database has to be cleaned up. That means deleting duplicate records, correcting errors, filling in empty fields and standardizing formats. It's like organizing a physical file room: you can't move disorganized boxes into a new office.
This is key for the new system to work without errors. If we migrate dirty or poorly structured data, we'll drag the problems into the new system, which can cause confusion and wasted time later.
4. Not everyone knows how to do it: you need expert hands
Migrating data in Odoo requires in-depth knowledge of the system. Knowing how to use it isn't enough; you have to understand how it works on the inside. If someone without experience does it, they can damage the information or leave processes incomplete that will be hard to detect later.
That's why it's always recommended that this work be done by expert Odoo consultants who have done migrations before. They know how to avoid common mistakes and how to deal with the unexpected problems that tend to come up during the process.
5. You have to run a lot of tests before saying “done”
Once the data is migrated, tests must be run to verify that everything works properly: sales, purchasing, reports, accounting, inventory, etc. You can't assume everything came out perfect the first time. This is where errors are caught that must be fixed before putting the system into production.
This testing process can take days or weeks, depending on the size of the system and how many modules are involved. But it's vital to make sure that when the new Odoo is switched on, everything is working 100%.
6. People also have to adapt to the new system
A new version of Odoo often changes how screens look or how certain tasks are done. That means the team needs training to adapt and keep working efficiently.
This change can create resistance or errors if it isn't accompanied by good communication and training. That's why migration isn't just technical; it's also a human process that requires time and care.
7. You can go over budget if it isn't planned well
Many companies think migrating is quick and inexpensive, but when errors, delays or special needs come up, costs go up. This happens especially when a complete prior analysis of the system and the data to be migrated hasn't been done.
That's why it's important to understand that migrating properly is an investment. Doing it badly to save time or money can end up costing much more later. The migration must be planned as a serious project, with defined stages, owners and timelines.
8. It's better to tell the truth from the start
Some companies promise migrations “in 48 hours,” but that only applies to very small systems with no customization. Most cases take weeks or even months to do right. Telling the client this from the outset builds trust and avoids frustration.
That's why this article aims to educate: if you're going to migrate Odoo, you should know it's a careful, meticulous process that has to be done responsibly. With an experienced team it can be done successfully, but don't expect overnight miracles.
9. Our step-by-step migration process
At Valtriom, we understand that every company is unique, which is why our migration process follows a clear, structured methodology. We start with a risk analysis, where we assess what could fail, which modules are involved and what critical dependencies exist. Then we carry out technical migration planning, where we define which modules should be upgraded first, which customizations need review and how the steps will be sequenced to ensure stability.
Next we move to the customization analysis and cleanup phase, where we review everything that has been modified in Odoo.sh and make sure every customization is documented and ready to be migrated. From there, we begin an intensive stage of testing, testing and more testing, simulating real scenarios to guarantee that everything works. Only when we're 100% sure everything is correct do we schedule and carry out migration day, with backups, real-time supervision and post-migration support. That's how we guarantee a clean, safe transition with no improvisation.
