Streamlining Enterprise Migration to Oracle Cloud with an API-Led Approach

Executive Summary

Moving from on-premises Oracle Financials and HCM systems to Oracle Cloud Financials and Oracle Cloud HCM is no small feat. It's a big step forward for organizations looking to enhance efficiency, scalability, and innovation. However, it also comes with challenges like managing complex integrations, ensuring data accuracy, and helping teams adapt to new systems.

This paper explains how an API-led approach can make this migration smoother, faster, and less risky. It also shows how Anahata, with its deep expertise and proven methods, can guide organizations through this journey using well-established industry practices.

Introduction

Oracle Cloud Financials and HCM offer modern, cloud-based solutions that improve agility, reduce operational costs, and unlock new capabilities like AI-driven insights and real-time reporting. For many organizations, moving to Oracle Cloud is necessary to stay competitive. But transitioning from older on-premises systems isn't always straightforward. It requires careful planning, strong technical expertise, and close collaboration between IT and business teams.

Anahata uses a structured, API-first approach to simplify the migration process and ensure that companies can quickly realize the benefits of Oracle Cloud.

Common Challenges in Migration

Technical Challenges

1. Integration Issues:

   Many older Oracle systems are tightly connected to other software tools, such as payroll platforms, reporting systems, or vendor management solutions. These integrations must work seamlessly in the new environment without interrupting day-to-day operations.

2. Data Problems:

   Over the years, legacy systems accumulate a lot of data—some clean, some messy, and some irrelevant. Transforming this data to fit Oracle Cloud's structures is a huge task.

3. Customizations:

   Older Oracle systems are often highly customized to meet specific business needs, and these customizations might not quickly transfer to the cloud.

Non-Technical Challenges

1. Change Resistance:

   People are used to working with their current systems. Adopting a new system means learning new workflows and interfaces, which can feel daunting for teams.

2. Compliance Concerns:

   Financial and HR data are highly regulated. Organizations must ensure that all migrated data meets industry and government standards.

3. Resource Gaps:

   Not every company has in-house experts who understand their legacy systems and Oracle Cloud, creating a need for experienced external partners.

What Is an API-Led Approach?

An API-led approach is about designing and building systems that focus on creating reusable connections, making it easier to move data and integrate processes between platforms. APIs (Application Programming Interfaces) are the "bridges" linking legacy systems with Oracle Cloud. This approach is organized into three layers:

1. System APIs:

   These APIs connect directly to your existing systems, extracting data without disrupting ongoing operations.

2. Process APIs:

   These handle data transformation and orchestrate data flow between systems, ensuring compatibility with Oracle Cloud.

3. Experience APIs:

   These are built for specific users, like HR managers or finance teams, providing them with tailored dashboards or apps that make accessing cloud functionality easy and intuitive.

How Anahata Speeds Up Migration

Anahata doesn't just build APIs; we follow a structured approach rooted in industry best practices. Here's how we help organizations make the leap to Oracle Cloud quickly and effectively:

1. Clear Roadmaps and Planning

• Identifying data sources, integrations, and custom workflows.
• Mapping dependencies to avoid surprises later.
• Collaborating with your teams to prioritize which systems and processes to migrate first.

We use tools like Oracle Management Cloud to analyze system performance and identify bottlenecks early.

2. Building Reusable APIs

• Pre-built Oracle Integration Cloud (OIC) connectors help speed connections to third-party tools like payroll systems or compliance platforms.
• We design RESTful APIs that are lightweight, secure, and easy to manage.

3. Cleaning Up Your Data

• Identify and remove duplicates.
• Standardize formats to match Oracle Cloud's requirements.
• Ensure all data meets regulatory standards before migration.

4. Agile Development Process

We break migration projects into smaller, manageable sprints. This allows us to test as we go and incorporate feedback from your teams, ensuring smoother implementation.

We also use tools like Postman for API testing and JMeter for performance validation to ensure your integrations hold up under pressure.

5. Strong Security Measures

Whether it's encrypting data in transit, implementing OAuth 2.0 authentication for APIs, or using role-based access controls (RBAC), we prioritize keeping your data safe.

6. Supporting User Adoption

One of the most overlooked parts of migration is getting teams comfortable with the new system. We build Experience APIs that simplify the interface for end-users, create sandbox environments for training, and provide detailed documentation so your teams are confident and prepared.

Case Study: Migration for a Telecom Tower Company

Background

A leading telecom tower infrastructure company decided to migrate its on-premises Oracle Financials and HCM systems to Oracle Cloud. The company manages over thousands of tower sites across multiple regions, and its systems needed to handle complex lease agreements, vendor payments, and payroll processes for thousands of employees.

Challenges

• Integrations with 80+ third-party systems, including site maintenance platforms, vendor management software, and payroll providers.
• Migrating decades of historical financial data, including lease contracts and compliance reports.
• Custom workflows for regulatory requirements in multiple countries.

Anahata's Solution

• Phase 1: Assessment - We mapped out all existing workflows and data sources. High-priority modules like General Ledger, Payroll, and Vendor Management were identified for early migration.
• Phase 2: API Design - System APIs were built to securely pull data from the legacy system, while process APIs handled data transformations, such as converting lease contract formats into Oracle Cloud-compatible schemas.
• Phase 3: Data Migration - We used Oracle GoldenGate to replicate data in real time while performing batch processing of historical records using Oracle Data Integrator.
• Phase 4: Testing and Training - After rigorous testing, we deployed Experience APIs that gave regional managers access to tower-specific financial dashboards. To ensure smooth adoption, role-based training sessions were conducted.

Results

• Migration time was reduced by 35% thanks to reusable APIs and automated data validation.
• 99.9% data accuracy achieved during migration.
• Automation of lease and vendor management processes, saving the company significant operational costs.
