Legacy application modernization services
Modernize the legacy applications your business relies on.
When routine changes become difficult, we help you work out what to keep, improve or rebuild. Our work covers established web and mobile apps, backend services, integrations and the move to the new version.
Let's talkScope
From the existing application to the next release.
Assess the application
Review the code, architecture, business rules and connected systems. Identify what is slowing delivery down and which changes would address it.
Refactor, upgrade or rebuild
A focused repair, a framework upgrade or a replacement can each be appropriate. We recommend an approach around the product, its users and the work it needs to support.
Migrate and release
Plan data migration, integration checks, testing and the cutover. Agree what needs to be checked before release and what would require returning to the previous version.
Rebuilding the applications people already rely on.
For MERP and PREP, emergency preparedness products from Safeguard Risk Solutions and HAPevolve, we rebuilt web applications, mobile apps and backend services, with DevOps, data migration and cutover in the same engagement.
People still needed to reach plans, contacts and procedures while we changed the software behind them. Our delivery team reports a switch without service interruption and 90% lower AWS costs after modernization.
Before implementation
Find out what the rewrite has to preserve.
Current behavior
Record the tasks, calculations and permissions customers rely on.
Dependencies
Identify integrations, scheduled work, exports and downstream consumers.
Migration checks
Examine the data and define how the migrated result will be reconciled.
Release decisions
Agree rollout options, rollback conditions and who owns the checks.
The records need to arrive with the users.
Before switching versions, we define how records, permissions and integrations will be checked, who makes the release decision and when to return to the previous version. Migration is part of the build, with time to rehearse and reconcile the result.
In other projects, that has meant preserving ZMatic’s spreadsheet rules in a custom ERP and connecting ECONT’s document access to existing sign-on and ERP permissions.
The system is the backbone of the company, and its smooth functionality and dependability is a testament to the work of Perspective Unity. They handle any issue with ease, delivering new components that are easy to handle by non-tech professionals, while also managing the work well.

Questions before we start
What is legacy application modernization?
Improving an existing application so it can support the next stage of the business. The work may involve code, architecture, interfaces, integrations or infrastructure, along with data migration and the transition for users.
Does modernization mean a complete rewrite?
Not necessarily. We assess the useful parts of the current system and the limits that prevent change before recommending what to retain, improve or replace.
Can the business keep using the current system?
We assess phased release and parallel operation where appropriate. Downtime, data synchronization and the cutover plan depend on the architecture and must be agreed for the project.
How much does it cost?
The estimate depends on the existing product, undocumented rules, integrations, data quality and the scope of change. We start by reducing the unknowns that affect the investment.
What is the current platform stopping you from doing?
Tell us what needs to change and what customers still rely on. We can assess the replacement options and the transition between them.
