Execute Your Mainframe Retirement: Secure Your Data,
Retain Actionable Reports, and Ensure Strict Compliance with AvenDATA
From IBM z/OS and BS2000 to bespoke mainframe applications, we help you execute a seamless legacy system retirement across all architectural generations. TSX-listed companies rely on our proven solution to permanently secure vital enterprise records, from production control to complex accounting workflows. At the same time, they significantly reduce maintenance costs and ensure strict compliance with Canada Revenue Agency (CRA) requirements.
The Challenge
Your historical mainframe records remain strategically critical, yet securing reliable access to them is becoming increasingly difficult.
During large-scale IT modernization, complex data centre consolidations, or the decommissioning of obsolete infrastructure, enterprises repeatedly face a high-stakes mandate.
Decades old mainframe architectures hold highly complex data structures. You must retain full control over these critical records to mitigate litigation risks, support strategic business analyses, and ensure strict CRA compliance.
Yet sustaining these obsolete systems drains significant capital. Hardware ages, software licences become increasingly expensive to renew, and critical internal IT expertise disappears.
Eventually, direct system access is lost entirely. Your enterprise data, however, must remain usable, available for analysis at any time, and fully audit-ready.
This is exactly where AvenDATA supports TSX-listed companies with its proven solution for mainframe legacy system retirement.

Your Mainframe Analytics Live On as Actionable Reports
in ViewBox
We do more than extract data from your mainframe architecture. We enable you to permanently use and trace this critical enterprise information within ViewBox, our industry-standard platform.
Our capabilities include:
- Accurate replication of essential standard reports and strategic business analytics
- Reconstruction of custom reports (including internally developed programs and lists)
- Comprehensive archiving of all critical source documentation (invoices, orders, and accounting records) to ensure full report traceability
Long before your IT modernization begins, we work with you to identify the exact reports you need to meet CRA requirements, support strategic business analyses, and comply with legal data retention obligations. You benefit from our extensive experience in mainframe legacy system retirement across diverse industries and highly specialized departments.
Within ViewBox, you can search, filter, and analyze these interactive reports years after your mainframe legacy system retirement, completely independent of the original system.
Whether you face CRA audits, internal investigations, or legal challenges, you remain audit-ready at all times. You have immediate access to clearly structured, filterable reports, with no need for expensive mainframe licences or maintenance of the original system.
Rapid Execution and Significant Economic Value (Measurable ROI),
Even for Large Mainframe Architectures
Mainframe legacy system retirement typically takes one to six months, depending on your enterprise data volume and architectural complexity. Our highly standardized methodology allows us to efficiently secure even the largest and most complex legacy environments.
For example, we have successfully migrated architectures exceeding several terabytes into ViewBox. These transitions secured all critical enterprise reports, the outputs of custom programs, and comprehensive documentation to ensure permanent audit readiness and strict CRA compliance.
With our established IT modernization framework, TSX-listed companies and global enterprises realize substantial financial gains. They significantly reduce maintenance costs by eliminating expensive licence fees for mainframe software, databases, and operating systems. They also lower infrastructure costs and the workload on internal staff.
In the vast majority of our enterprise projects, clients achieve a return on investment (ROI) in under one year. This fast payback is driven by measurable savings on software licences, infrastructure, and internal IT resources.

Strategic System Analysis
The first step of your mainframe legacy system retirement is a rigorous assessment of your existing architecture. This comprehensive analysis shapes your IT modernization roadmap and gives you full transparency regarding project timelines, enterprise data scope, and the exact investment required.
We carefully evaluate your technical and operational architecture, including:
- Access methods for your current mainframe environment
- Database architecture, including the type, structure, and scale of your databases and files (such as IMS, Db2, and VSAM)
- Scope and strategic relevance of your existing applications and reports
- System customizations, such as internally developed programs and custom enterprise interfaces
To give you decision-making certainty and reliable budget planning during this critical transition, we deliver these findings as a binding fixed-price proposal. TSX-listed companies and global enterprises rely on this approach to mitigate litigation risks and ensure strict CRA compliance from the very start of their mainframe retirement.

IT Modernization Execution
Following your comprehensive system analysis, we launch your legacy system retirement with a highly structured approach and clearly defined milestones.
We begin with a strategic kick-off meeting to align your team on all critical organizational and technical requirements. From that point on, our experts take over the technical work:
- Establishing highly secure access to your legacy mainframe environment
- Extracting and migrating all critical enterprise records
- Accurately replicating your essential standard reports and custom analytics
- Producing comprehensive, audit-ready documentation to ensure lasting CRA compliance
Our senior project managers lead this transition from end to end. You stay focused on your core business objectives, and we significantly reduce the strain on your internal IT resources.
To complete the project, we carry out rigorous structured testing and executive sign-off phases. This ensures that every enterprise record is permanently secured, fully usable, and audit-ready. TSX-listed companies and global enterprises rely on this proven solution to reduce maintenance costs and mitigate litigation risks.

Final IT Modernization Outcomes
Upon project completion, all critical tables, legal documents, and vital enterprise reports from your mainframe architecture are available in ViewBox, our industry-standard platform.
ViewBox is a web-based data discovery platform. It gives your authorized personnel rapid, highly secure, and fully traceable access to your archived enterprise information for decades after your legacy system retirement.
Your strategic advantage: we accurately reconstruct all critical standard analytics and custom reports. You can continue to carry out vital operational analyses and maintain strict CRA compliance, entirely without direct mainframe access.
Following the successful deployment and executive sign-off of ViewBox, you can significantly reduce maintenance costs by permanently decommissioning your obsolete mainframe environment.
At project closure, we deliver a comprehensive, audit-ready documentation package. It details every phase of the work to ensure full transparency regarding:
- The architecture and methodology of your enterprise data migration
- The mapping and structure of all archived enterprise content
- The execution of structured testing and final acceptance phases
We also log every project milestone in our secure Jira ticketing system, which gives you a complete audit trail. It runs from the initial data export through final executive sign-off to the deletion of your source system. TSX-listed companies and global enterprises rely on this proven solution to mitigate litigation risks, ensure permanent audit readiness, and provide full transparency for all third-party auditors.
ViewBox Enterprise
Use Archived Data from Legacy Systems Securely and Quickly
With ViewBox Enterprise, AvenDATA offers a powerful platform for secure access to data from decommissioned ERP systems and other legacy applications. The solution combines modern search and analysis functions with high performance, comprehensive security mechanisms, and AI-powered features.
ViewBox Enterprise ensures that your archived data:
