Application Modernization Consulting

Decide how to modernize a business-critical application without stopping the business that runs on it. Cognativ assesses the code, architecture, and usage, then sets the approach and plan your team or ours can deliver.

Case result: a regional telecom company kept all of its key accounts within 12 months of its platform rebuild.

An Application Assessment Across Three Layers

Before choosing an approach, our application modernization consulting looks at the application from three angles, because the right answer depends on all of them.

Three layers of an application assessment

Code

Quality, test coverage, outdated frameworks, and the knowledge needed to change it.

Architecture

How the application is structured, integrated, and deployed.

Usage and value

Who relies on each part, how often, and what it is worth to the business.

Application Modernization Consulting That Picks the Least Disruptive Path

The assessment feeds one decision: how much to change. We recommend the least disruptive approach that removes the real constraint. The three inputs below are the constraint the application creates today, the assessment of its code and architecture, and your budget and risk.

Three inputs to a modernization approach

Constraint

What the application blocks today: change speed, scale, security, or cost.
Assessment

The state of the code, architecture, and usage.
Budget and risk

What the business can invest and how much disruption it can absorb.

Approach

Upgrade
Refactor
Re-architect

Legacy Application Modernization in Stages

Modernization runs in stages, with old and new parts working side by side until the switch is safe. Cognativ rebuilt a subscription platform that then regained growth and modernized a B2B marketplace's search and bulk ordering.

Signs an Application Needs Modernization

Changes take weeks that should take days, few people understand the code, the framework or platform is out of support, the application cannot scale with demand, or security reviews keep finding the same issues.

Each sign points to a different constraint, which is why the assessment comes before the approach.

Application Modernization Consulting Questions

What to expect before you start. The answers cover what application modernization is, how it differs from an IT strategy, rebuild versus refactor and keeping the application running.

What is application modernization?

Application modernization updates an existing application, its code, architecture, or platform, so it can keep up with business needs, scale, and security standards.

How is this different from an IT modernization strategy?

An IT modernization strategy covers the whole portfolio of systems. Application modernization consulting focuses on one critical application and how to modernize it.

Should we rebuild or refactor?

Refactor when the core logic is sound and specific parts limit you; rebuild when the code cannot support what the business needs. The assessment decides.

Can the application keep running during modernization?

Yes. Staged modernization keeps the current application in service until each part is replaced and proven.

Do you deliver the modernization too?

Yes. Cognativ can carry out the modernization or support your developers through it.

How does an engagement start?

With a free first consultation about the application you need to modernize, then a short assessment with a fixed scope and fee agreed before work begins.
