Success Story

Channellock unleashes efficiency with Allari's ITaaS seamless JDE 9.2 upgrade and advanced automation

Channel Lock Logo - Legacy Applications Modernization Client


As Channellock embarked on a modernization journey, upgrading their primary ERP from JD Edwards World software to JDE Enterprise 9.2, the team encountered a skills gap in System Administration/CNC/DBA necessary for the upgrade. The limited local supply of JDE talent posed a significant challenge for ongoing support post-upgrade. Their initial solutions evolved from basic system administration to a comprehensive suite of JDE services and cybersecurity solutions.


Allari stepped in to bridge the skill gap and support Channellock's modernization efforts:
  • Transitioned CNC and DBA services to Windows/SQL platform from AS/400.
  • Implemented AllOut Security for simplified user access and administration.
  • Replaced native JDE scheduler with Tidal Automation Software.
  • Managed the transition to Microsoft SQL Server database from DB2.
  • Extended post-go-live support in JDE CNC, database, development, and functionality.
  • Ensured JDE remained updated with latest versions.
  • Upgraded helpdesk software and services for efficient issue resolution.
  • Managed Darktrace AI Cybersecurity for proactive monitoring, detection, and remediation.
  • Implemented Microsoft BI for enhanced business intelligence in Sales.
  • Augmented staff for system administration and cybersecurity analysis.
  • Automated Penetration testing and implemented quarterly Vulnerability Management and Patching to reduce cyber risk significantly.


Channellock's partnership with Allari marks a significant stride in efficiency and security, fortifying its manufacturing and US legacy.
  • Successful go-live for JD Edwards 9.2 and subsequent Tools Upgrade.
  • 24/7 JDE production support across various domains at the cost comparable to 1 FTE — a task requiring 4-6 FTEs otherwise.
  • Tidal Automation eliminated report execution wait times, with real-time error notifications enabling quick resolutions.
  • Regular Channellock-Allari strategy meetings to address a broader scope of challenges and swiftly resolve service issues.
  • 24/7 automated monitoring with JDE Orchestrator, saving 275 hours annually.


Common questions about legacy systems modernization

How do I modernize an old system or application?

Modernizing an old system or application involves: Assessment and Planning: Evaluate the current system's architecture, performance, and security. Define modernization objectives, considering budget, operational limits, and risks like data loss or downtime. Modernization Strategy: Options include: Rehosting: Minimal changes, often to the cloud. Refactoring/Rewriting: Align with modern architectures. Replatforming: Adapt to a new platform, optimizing features. Replacing: Implement a new solution. Technology Selection: Choose suitable technologies and platforms. Migration Plan: Outline detailed migration steps. Development and Testing: Implement and test for functionality and compatibility. Data Migration: Transfer data ensuring integrity. Deployment: Deploy in production, with rollback strategies. Training and Support: Train users, provide ongoing support. Continuous Improvement: Regular updates based on feedback and new technologies.

What are the best application modernization techniques?

Choosing the best application modernization technique depends on your organization's specific needs and existing infrastructure. Popular methods include: Rehosting (Lift-and-Shift): Move applications to a new environment, typically the cloud, without major changes. Ideal for quick migrations, reducing costs, or improving scalability. Refactoring: Optimize existing code without altering functionality, useful for enhancing performance or maintainability. Rearchitecting: Major architectural changes to improve scalability or performance, often shifting to microservices. Rebuilding: Rewrite the application entirely for modern features or technologies. Replacing: Substitute with a new application or commercial solution when current ones are inadequate. Containerization: Encapsulate in containers for enhanced portability and scalability. Using Platform as a Service (PaaS): Develop and manage applications on cloud platforms for rapid deployment.

What are the challenges of successful digital transformation?

Digital transformation presents several challenges: Cultural Resistance: Overcoming employee and management apprehension towards new digital methods. Lack of Clear Strategy: Need for a cohesive digital strategy aligned with business goals. Budget Constraints: Significant investment needs and complex ROI justification. Talent Gap: Recruiting and retaining digital experts in a competitive market. Technological Complexity: Choosing and integrating new technologies with legacy systems.

Scaling and Sustainability: Expanding digital initiatives effectively and sustainably. Change Management: Managing transition smoothly, including stakeholder alignment. Rapid Technological Change: Keeping pace with evolving digital landscapes. Regulatory Compliance: Navigating complex legal and regulatory environments.oyment.

What are the seven Rs of cloud app modernization?

The 7Rs of cloud application modernization are strategies for updating or migrating legacy applications to the cloud: Rehost (Lift and Shift): Move applications to the cloud unchanged. Refactor (Repackage): Make minimal changes for cloud compatibility. Rearchitect (Redesign): Overhaul architecture for cloud-native features. Rebuild (Rewrite): Completely rewrite using cloud-native technologies. Replace (Drop and Shop): Substitute with a cloud-native app, often SaaS. Retain (Revisit): Keep in the current environment, with future reassessment. Retire (Remove): Decommission obsolete applications.

What is application modernization?

Application modernization is the process of updating older software to new computing methods, including contemporary frameworks and infrastructure. It typically involves: Replatforming: Migrating an app to a new platform, like the cloud, enhancing performance without changing its architecture. Refactoring: Optimizing existing code to improve performance and maintainability, keeping the same external behavior. Rearchitecting: Overhauling the app's architecture for greater modularity, like shifting to microservices. Rebuilding: Redesigning the app from scratch while maintaining its original purpose. Replacing: Switching out outdated software with new solutions that better meet current business needs and technological standards.

What is the best automated tool set for legacy modernization?

The optimal automated toolset for legacy modernization varies based on project specifics, existing tech, future goals, and budget. Key tools include: Cloud Migration: AWS Migration Tools, Azure Migrate, Google Cloud Migrate. Containerization/Orchestration: Docker, Kubernetes, Red Hat's OpenShift.
