How to move to a new business system without unnecessary risk

Concern about changing a company system is understandable. It is not only about new software.

The current solution holds data the company relies on. People have an established way of working. Other services may be connected to the system, and an outage or a mistake during the transition can affect everyday operations.

That is why it is not a good idea to start with the question of how to switch the old system off as quickly as possible.

It matters more to plan how to get the new system safely into real operation.

First you need to know what is changing

Before development or migration, it is important to map the current state.

Where is the data stored? Which information has to be transferred? Which tools are connected to the current solution? Which processes must keep working without interruption during the change?

It is equally important to find out what works well in the current solution.

A new system does not have to mean throwing everything old away. It may be better to keep some tools or parts of the process and simply connect them to the new solution.

You do not have to change everything at once

One way to reduce the risk is to start with a specific part of the system.

You choose an area with a clearly defined benefit that can reasonably be separated from the rest. It goes to the people who will actually work with it, and it is verified in everyday operation.

Only real use reveals the things that may not be visible during design.

That is why at Cabakorp we work with a pilot after the analysis. It makes it possible to verify the proposed direction before it is extended to other parts of the company.

Data deserves a plan of its own

Data migration is not just technically copying one database into another.

Older systems may contain duplicates, out-of-date details or information kept in a form that makes no sense in the new solution.

Before the transfer, you therefore have to decide which data should carry on, in what form, and how to verify that it was transferred correctly.

The specific approach depends on the system. Sometimes data can be transferred gradually; elsewhere a one-off migration is more suitable. In some cases both solutions can run side by side for a while.

There is no universal recipe.

The people who use the system decide whether it is accepted

A technically correct solution can fail if it complicates people's everyday work.

That is why it makes sense to involve future users during development and to collect their feedback. Not only once the whole system is finished and changes are considerably more expensive.

The goal is not to preserve every current habit. But the people who do the work every day often spot an unnecessary step, or a situation the design did not account for, very quickly.

The transition ends only when the new system works in practice

Deploying a new application is not a goal in itself.

You have to verify that people can genuinely work, that the data is in order, that the connections function and that any problems can be resolved quickly.

And even then the work on the system does not end.

The company keeps changing, new requirements appear and the surrounding services change. That is why, for the systems we develop, we also plan for their subsequent operation, maintenance and further development.
