Transforming Your Legacy Systems for the Future

At Apex 1, we specialize in modernizing and optimizing legacy technologies that are integral to the operations of many organizations. From COBOL and Lotus Notes to DB2 databases, Mainframes, and IBM systems, we have the expertise to transform these critical technologies to meet today’s business demands while positioning them for future success.
Our Legacy Technology Development services help organizations in industries such as banking, retail, healthcare, and pharma optimize their IT infrastructure, reduce technical debt, and future-proof their operations.

Legacy Technology Areas We Focus On


1. COBOL-Based Systems

COBOL (Common Business-Oriented Language) is one of the oldest programming languages still in use today, particularly in mainframe environments like banking and insurance. While many legacy COBOL systems still power mission-critical applications, they can be costly and difficult to maintain.

Examples of COBOL Technologies
COBOL on IBM Z Series (Mainframe)
COBOL in IBM iSeries (AS/400) environments
COBOL applications used for legacy ERP systems (e.g., SAP R/3)
OBOL-based banking and financial transaction systems
Apex 1’s Capabilities:
Code Refactoring & Optimization:
Apex 1 helps clients refactor COBOL code to ensure it is optimized for modern environments and easier to maintain.
Integration with Modern Systems:
We specialize in integrating COBOL-based systems with modern cloud, ERP, and CRM platforms.
Migration to Cloud or Modern Platforms:
We help clients migrate their COBOL applications to cloud platforms or modern software stacks, ensuring operational continuity with minimal risk.
2. Lotus Notes

Lotus Notes was once a leading enterprise collaboration and email platform, but it has since been replaced by more modern solutions. For organizations still using Lotus Notes, migrating to a more agile, cloud-based platform is critical for security, efficiency, and scalability.

Examples of Lotus Notes Technologies:
Lotus Notes/Domino-based email systems
Lotus Notes-based business applications and workflows
IBM Notes Client (formerly Lotus Notes Client)
for document management and collaboration
LotusScript
(scripting language for Lotus Notes applications)
Apex 1’s Capabilities:
Migration to Microsoft 365 or Google Workspace:
We help businesses move from Lotus Notes to more modern collaboration platforms such as Microsoft 365 or Google Workspace, ensuring no data loss and minimal downtime.
Business Process Modernization
Our experts refactor and modernize Lotus Notes-based business applications, migrating them to more scalable, flexible systems.
Legacy Application Migration:
We assist in migrating Lotus Notes applications to modern frameworks like Salesforce, SharePoint, or custom cloud solutions.
3. DB2 Databases DB2

originally developed by IBM, remains a dominant database management system, especially in legacy mainframe and IBM iSeries (AS/400) environments. However, as organizations increasingly move to cloud solutions, optimizing DB2 databases for scalability, performance, and integration is critical.

Examples of DB2 Technologies:
IBM DB2 on Mainframe (z/OS)
DB2 on IBM iSeries (AS/400)
DB2 for z/OS (for transactional processing)
DB2 on Cloud (IBM Cloud Databases for DB2)
Apex 1’s Capabilities:
DB2 Database Optimization:
We optimize DB2 databases for performance and scalability, enabling faster transaction processing and smoother data flow.
Cloud Migration for DB2:
We specialize in migrating DB2 databases to cloud platforms (AWS, Azure, IBM Cloud) while maintaining data integrity and security.
Data Integration:
Apex 1 integrates DB2 databases with modern big data systems, providing enhanced analytical capabilities for business intelligence and decision-making.
4. Mainframes & IBM Systems

Systems Mainframes, particularly IBM Z Series and IBM AS/400, are foundational in sectors like banking, insurance, and retail. These systems run mission-critical applications but can be difficult and expensive to maintain. IBM iSeries (AS/400) and IBM Z Series (mainframes) continue to host key business applications, including banking transaction systems, retail inventories, and healthcare management platforms.

Examples of Mainframe & IBM Technologies:
IBM Z Series Mainframes
(e.g., IBM Z15, Z13, Z14)
IBM iSeries/AS/400
(e.g., IBM Power Systems)
IBM DB2 for z/OS
(used in mainframe environments)
IBM CICS
(for transaction processing on mainframes)
IBM WebSphere
(middleware for legacy systems)
IBM MQ
(for messaging and communication between mainframe and modern systems)
Apex 1’s Capabilities:
Mainframe Modernization:
We help migrate and optimize legacy applications running on IBM Z Series and IBM iSeries systems, modernizing them for cloud or hybrid cloud environments.
Mainframe-to-Cloud Migration:
Apex 1 specializes in mainframe-to-cloud migrations, ensuring a smooth transition to cost-effective, scalable cloud environments while preserving legacy functionality.
Legacy System Integration:
We integrate mainframe and IBM iSeries systems with modern enterprise tools like ERP systems or CRM platforms, enhancing efficiency and enabling cross-platform workflows.
Success Stories

1. Banking

A leading global bank had a large legacy system running on COBOL and DB2 on IBM Z Series mainframes for transaction processing. These systems were vital to their day-to-day operations but were costly and inflexible. Apex 1 modernized the bank's legacy systems, refactoring COBOL applications and migrating their DB2 databases to the cloud. This enabled the bank to reduce operational costs, improve transaction speed, and scale more efficiently.

Result:
• Reduced IT operational costs by 30%
• Faster transaction processing with improved database performance
• Seamless integration with modern cloud-based analytics platforms


2. Retail

A global retail chain still relied on IBM AS/400 (iSeries) for inventory and supply chain management. However, the system lacked scalability and integration with their modern sales platforms. Apex 1 helped the retailer migrate their legacy AS/400 systems to a hybrid cloud platform, integrating them with real-time inventory tracking and modern sales systems.


Result:
• Improved inventory management with real-time updates
• Enhanced customer experience by linking the new system with online sales platforms
• Increased operational efficiency and reduced downtime
3. Healthcare

A leading healthcare provider relied on an aging COBOL-based mainframe system for patient management and medical records. Apex 1’s team refactored the COBOL code and migrated their DB2 databases to a secure cloud infrastructure, allowing them to better handle patient data, improve regulatory compliance, and enhance overall operational efficiency.


Result:
• Increased data security with encrypted cloud-based storage
• Improved healthcare outcomes through faster access to patient data
• Reduced compliance risks with modernized data management processes

4. Pharma

A pharmaceutical company was using Lotus Notes for collaboration and project management. This system was outdated and difficult to maintain. Apex 1 migrated the company’s Lotus Notes applications to Microsoft 365 and integrated them with their research data systems. This allowed for more seamless collaboration and improved research workflows.

Result:
• Enhanced collaboration across global teams with Microsoft Teams and SharePoint
• Reduced operational overhead by eliminating the need for Lotus Notes maintenance
• Streamlined research processes, improving the time-to-market for new drugs
