Legacy to Cloud. Unified. Instant. Safe.

Modernise without replacing what already works.

Legacy and cloud running side by side

SOLUTION 01
LEGACY & CLOUD COEXISTENCE

Trapped Between Two Undesirable Choices

Keep Legacy As-Is

Continue operating legacy systems and limit innovation.

Replace Everything

Undertake large-scale replacement with significant cost, risk and uncertainty.

Across government and enterprise, pressure is accelerating: faster digital transformation, better customer experiences, cloud adoption, and AI-driven innovation. Yet the systems processing an organisation’s most critical transactions often remain legacy platforms — reliable, but hard to access, integrate and govern.

Neither option delivers the outcomes executives need. Modern organisations require a third path — one that enables innovation without destabilising the systems that run the business.

Replacement Is Slow. Extraction Is Risky.

Large-Scale Replacement

  • Multi-year initiatives that demand major investment before delivering value.
  • Millions of lines of code and thousands of embedded business rules make replacement high-risk.
  • Decades of evolved integrations are easy to underestimate — and costly to unwind.

Traditional Batch Extraction

  • Creates additional copies of sensitive data instead of enabling modernisation.
  • Increases governance complexity across duplicated data stores.
  • Introduces latency that limits real business value and slows decisions.

A Coexistence Modernisation Strategy

CCA and OpenText synchronise and make enterprise data available in real time — while core operational platforms keep performing the functions they already do well.

Business-Outcome-Led, Not Big-Bang IT-Led

  • Value is delivered incrementally, aligned to real business needs — not saved up for a single go-live.
  • Replaces the traditional multi-year, big-bang replacement that only pays off at the very end.
  • Each phase is scoped around a specific, measurable business outcome.

Significantly Reduces Delivery Risk

  • Avoids the risk of untangling deeply embedded complexity within legacy applications.
  • Reduces exposure to the growing shortage of legacy platform skills and expertise.
  • Minimises disruption to mission-critical systems that the business depends on daily.
  • Byproduct benefits: faster digital services, accelerated analytics, cloud enablement, and AI-ready data — delivered along the way, not just at the end

Mainframe core systems and modern cloud platforms both running and kept continuously in sync, so modernisation happens without disrupting mission-critical systems

Real-Time Coexistence, End to End

Trusted, continuous synchronisation between legacy platforms and modern environments.

Live transaction twin Legacy systems provide committed change records to Rocket Data Replicate and Sync. RDRS captures and transforms those changes, the CCA Data Connector and OpenText Voltage SecureData protect sensitive values, and protected records are applied to modern platforms. A verified return path confirms current state.

Purpose-Built Components, Working as One

OpenText Voltage Data Security Platform (DSP)

Discovers and automatically classifies structured data assets — what exists, where it resides, and how it should be governed.

Rocket Data Replicate and Sync (RDRS)

Real-time change data capture and synchronisation across legacy and modern environments, as changes occur.

CCA Secure Data Connector

Integrates real-time replication with protection services so sensitive data stays protected throughout synchronisation.

OpenText Voltage SecureData

Encryption, format-preserving encryption, tokenisation and policy-driven controls — without impacting usability.

What the Solution Delivers

Real-Time Synchronisation

Trusted data movement between legacy and modern platforms.

Protected-by-Design Pipelines

Sensitive information protected before it leaves source systems.

Cloud Enablement

Support cloud adoption without additional governance risk.

AI Readiness

Trusted, governed data foundations for AI initiatives.

Incremental Transformation

Modernise progressively, delivering value at each phase rather than in a single go-live.

Outcomes That Matter to the Business

Accelerate Time to Value

Deliver outcomes in months rather than years.

Reduce Transformation Risk

Avoid disruptive replacement programs.

Preserve Existing Investments

Continue leveraging proven operational systems.

Enable Innovation

Make enterprise data available for cloud, analytics and AI.

Strengthen Governance
