Modernization solution
Mission-critical, under control
We migrate, modernize and optimize your legacy systems, reducing operational risk and TCO, without interrupting operations.
Let's talk about your ecosystem

Architects of Business Continuity
The critical systems of banking, payments, insurance, government and telecom keep running reliably, but they no longer meet the demands of today’s market. Maintaining legacy has stopped being a technical challenge and become a direct threat to business continuity.
A silent threat
While the system keeps processing transactions, the risk stays invisible: the knowledge of those who built it fades and hidden dependencies pile up.
Regulatory and market pressure
Open Finance, Brazil’s DREX and increasingly strict cybersecurity regulations demand an agility that legacy architectures cannot deliver.
Rising cost and fragility
Obsolete hardware, costly licenses and the scarcity of legacy specialists drive up the cost and risk of every change.
The cost of the status quo is not zero
Postponing modernization accrues technical debt and raises the probability of a critical failure. That cost is real, only invisible until it is too late.
We treat legacy evolution as an evolutionary, low-risk strategy. The continuity of your operation is non-negotiable.
Zero disruption
Non-intrusive techniques and parallel processing between the current platform and the new one: the operation is never exposed during the transition.
Proven methodology
A structured cycle (assessment, architecture, execution, certification and support) designed to maximize business continuity at every phase.
Reversibility and control
A rollback plan at every cut-over and automated certification ensure a transition that is transparent to users.
Sovereignty and knowledge
Deployment on cloud, on-premises or hybrid according to your data-residency requirements, with knowledge transfer so your team operates autonomously.
EBS has multiple proven experiences globally. Since a large part of these mission-critical projects require strict confidentiality, we share here only a few publicly known cases as a reference.
French Development Agency (AFD)
A public financial institution that chose CobolCloud and EBS’s expertise to modernize its critical COBOL applications, demonstrating the power to transform legacy systems while maintaining business continuity.

Responsibility for the technology and the operations sat on the client’s side: a transactional payments core had to be moved off a legacy environment without stopping the business. That perspective, of carrying the risk and not only the delivery, is what JAAB brings to other companies in the region.

Mainframe Migration
Complete migration of legacy mainframe applications and data to modern platforms, minimizing risks and downtime.
Application Modernization
Transformation of legacy applications into modern architectures, maintaining critical business logic while improving performance and maintainability.
Replatforming
Transformation of systems running on obsolete environments to modern platforms, reducing operational costs and improving the evolution capacity required by the industry.
Decades of knowledge turned into a workbench that industrializes the transformation and reduces project risk.
Workbench for rehosting, transformation and certification of applications.
Batch process orchestration on the target system.
Universal table management, replacing Spitab or DPT.
APIfication and replacement of Tuxedo / CICS.
Is your legacy core a latent risk? Let’s assess it together.
Let's talkMeasurable business results, not just technical improvements.
TCO Reduction
Dramatic reduction in total cost of ownership through elimination of expensive mainframe licenses and specialized hardware.
Increased Agility
Significant improvement in time-to-market with modern development and deployment processes.
Risk Mitigation
Elimination of risks associated with obsolete hardware and scarcity of skills in legacy technologies.
