Software Migration Services: Legacy System Upgrades

Why would you need to worry about software migration? In today’s fast-moving tech world, keeping up is key. Upgrading old technology to new solutions is more than an update—it’s a smart way to boost efficiency, security, and competitiveness. We help businesses move from outdated systems to modern ones. Over the years, we have built significant expertise in managing migration projects.

Legacy Application Migration: Many companies use older applications. They often handle key processes and are critical for the business. However, as the organisation has grown, they have become outdated and may limit growth. Sometimes, it is possible to replace them with off-the-shelf products. But sometimes, these custom-made applications manage processes unique to the organisation.

We offer a complete plan to update these applications. We can move them to new platforms without interrupting business. For example, we can turn an old CRM system into a cloud-based one, giving more flexibility, better integration, and a better user experience.

Software as a service SaaS: Do you provide a SaaS solution to others that have become technically outdated? Where did they develop fast to meet critical needs? Are there technical debts? You may need to upgrade to newer technologies.

Framework and Library Upgrades: Old technologies can become problems if not updated. For example, many companies still use AngularJS. AngularJS reached its end of life a few years back and is no longer supported. Migrating to the latest version of Angular may work. Or it may work to change to other frameworks—E.g. React and Vue, which are also suitable for building modern user interfaces.

Many old applications don’t work well on mobile devices. We can update the software to work well in mobile browsers. If required, we can develop mobile-friendly apps so they adjust based on the device used. We know that not everyone understands the tech behind their systems. We can check and suggest how to make your technology future-proof.

What is Software Migration?

Software migration means moving a software system from one place to another. This includes transferring data, functions, and settings from the old system to the new one. There are different ways to do this:

Big Bang Approach: Move the entire system all at once.
Phased Approach: Move the system in stages, bit by bit.

There are various types of software migration:

Platform Migration: Moving a system from one operating system to another, like Windows to Linux.
Database Migration: Transferring data from one database to another. Examples of data migrations are from MySQL to PostgreSQL or MS SQL.
Technology Migration: Changing the system’s architecture, for example, from a single extensive application to a microservices architecture.
Version Migration: Upgrading the software’s frameworks and libraries to newer versions.
Cloud Migration: Moving the system’s resources, like servers and databases, from on-site infrastructure to a cloud provider like AWS or Azure.
Language Migration: Changing the software’s programming language might involve rewriting the code in a new language for better features or performance. This may be Microsoft Access to a modern Web environment like Dot Net or NodeJS.
Framework Migration: AngularJS to Angular 18, React, or Vue.

Each type can present its challenges.

What are the challenges?

The software migration process can be challenging for organisations. There are different challenges:

Data loss during software migration;
45% of companies lose data due to incompatible formats or errors.
Employees may resist the new system, which can lower productivity.
Cost overruns are common, too; 75% of projects go over budget due to unexpected issues or extra customisation needs.
Migration can cause temporary system downtime, disrupt business, and lead to revenue loss. For example, employees might be unable to use email during the upgrade process, affecting communication.
Integration issues can arise when old systems don’t work well with new software, causing data problems and disruptions of business operations.

To overcome these challenges, a sound project plan is essential for a smooth transition.
