Software Development
Keep the Software That Runs Your Business - Modernise It.
For many organisations, their most valuable software isn’t the newest application—it’s the business system that’s been running successfully for years.
The problem is that many of these systems are now running on outdated Linux platforms, legacy versions of PHP and MySQL, unsupported Apache releases, and ageing infrastructure. While the application still performs an essential business function, the technology behind it has reached end-of-life, creating security, reliability and compliance risks.
ERP platforms will offer you their multi-purpose platform and a heft configuration and migration project. Most software development companies will recommend one solution: rewrite everything from scratch. Whilst that is a one way forwards, ITSP offer another option.
We specialise in modernising heritage business applications, allowing organisations to preserve the business logic that has evolved over many years while bringing the underlying technology up to modern standards.
Our Expertise
We have extensive experience working with business-critical web applications built on technologies such as:
· PHP, Perl
· MySQL / MariaDB, MongoDB, Postgres
· Apache
· Linux
· Legacy LAMP environments
· Custom in-house business applications
These applications often continue to perform exactly the job they were designed for—but are held back by outdated platforms, unsupported software versions and user interfaces that no longer meet modern expectations.
Rather than replacing years of proven business functionality, we carefully modernise what’s already working.
What We Do
Platform Modernisation
We migrate applications from unsupported Linux distributions and legacy server environments onto modern, secure platforms.
PHP & Database Upgrades
Applications written many years ago often rely on deprecated PHP functions or outdated MySQL features.
We methodically refactor the application so it operates correctly on current supported versions of PHP and modern database platforms.
Security Improvements
Older applications frequently contain vulnerabilities simply because software standards have changed.
We improve security by:
· Updating authentication mechanisms
· Replacing deprecated libraries
· Eliminating insecure coding practices
· Applying modern encryption standards
· Hardening server infrastructure
Bug fixes and additional functions
Most heritage business applications have long term bugs and features on the wishlist that have never been implemented.
We work with your users to fix bugs and add features that improve the functionality of the application and make it more useful to the business.
User Interface Refresh
Many heritage applications still provide tremendous business value but look dated.
We can modernise the interface without changing the business processes your users already understand.
The result is software that feels contemporary while retaining the workflow your staff rely upon.
These applications often continue to perform exactly the job they were designed for—but are held back by outdated platforms, unsupported software versions and user interfaces that no longer meet modern expectations.
