Legacy application modernization that makes aging software safe to change
Infoloop's legacy application modernization services update aging business software, often after the original vendor has left. We audit the codebase, rank the risks and upgrade it in small, reversible releases. Your teams keep working throughout the project. You receive a written risk assessment, then the scope, budget and timeline in writing before work begins.

How we work
Our legacy modernization process
Four stages, with a code assessment before any quote.
01Free discovery call
You describe the application, its known failures and the changes you need. We give an honest view on whether to modernize or replace it, with no obligation to proceed.
02Technical assessment
We review the codebase and infrastructure with read-only access for a fixed number of days. You receive a ranked risk register and the cost of each option.
03Written plan and budget
You select an option from the assessment. We turn it into a written plan with milestones, a timeline and the cost. The cost is a fixed price when the scope is clear, or an hourly rate with an estimate. Work begins only after your approval, and any change in scope is priced first.
04Small releases, then support
Changes ship in small releases, each with a tested rollback. At handover, your team receives complete documentation. Alternatively, we provide monthly support with monitoring, fixes within agreed response times and a monthly report.

What our clients say
The difference is they did not leave. Every month we get a report, fixes and one clear next step.
More cars through the same bays, with fewer staff hours on admin. That is growth that did not cost us a new building.
They shipped our support agent in five weeks and it has run ever since. Response time dropped from hours to two minutes.
FAQs
Questions about legacy app modernization
Straight answers. If yours is not here, ask us on the call.
What is legacy application modernization?
Legacy application modernization means updating the software your business depends on, so it is secure and safe to change again. It can involve framework upgrades, a move to supported cloud hosting or replacing one module at a time. Your staff continue using the application throughout.
Should we rewrite our legacy software or modernize it?
Usually modernize, because the existing application already handles years of edge cases. A rewrite makes sense when the data model is flawed or the platform has no upgrade path. We price both options in writing, and you decide.
What does a legacy modernization assessment cost?
The assessment is a small fixed fee, agreed in advance. We spend a set number of days in the codebase. You receive a prioritized risk list and the cost of each option, in writing, and the report is yours either way. The work then has a fixed price for a clear scope, or is billed hourly against an agreed estimate.
Can you modernize legacy software without stopping the business?
Yes. We deliver in small releases, not one large cutover. Each new component runs behind the screens your staff already use, and switches over once it is verified. For a legacy system migration, we rehearse the move on a copy of your data and maintain a tested rollback plan.
Can you take over code the original developer left behind?
Yes. Most applications we inherit have no documentation and no automated tests. We start with read-only access inside your accounts and a copy of your data with personal details masked. Next, we add automated tests around the most frequently changed areas and wherever a failure costs money. We document the system as we go.
What happens when the modernization work is finished?
You choose. Your team can take it over, with the code, documentation and logins already in your accounts. Or we support it through an optional monthly plan, with monitoring, fixes within agreed response times, updates and a monthly report.
