Several businesses are aiming at smooth migration from Informatica PowerCenter to Informatica Intelligent Cloud Services (IICS). This migration brings the benefits of the newest business opportunities and scalable operations of the cloud platform.

This migration is made easy with the help of professional solution providers focusing on dedicated planning and execution. Here is a detailed and comprehensive guide to focus on different aspects of this migration.

Migrating from Informatica PowerCenter to Informatica Intelligent Cloud Services (IICS) offers enhanced scalability and modern cloud benefits. Expert solution providers streamline this transition with careful planning and execution.

PowerCenter to IICS Migration :

The migration of Informatica PowerCenter to Informatica Intelligent Cloud Services (IICS) is accompanied with different professional benefits. It includes increased business scalability, improved employee performance, and less investment in infrastructure costs.

However, the migration process requires thorough planning and careful execution to ensure a seamless transition for modern businesses.

IICS Migration Strategies and Automation

1. Manual Rebuilding

This approach involves manually recreating mappings, workflows, and sessions in IICS. It is suitable for small-scale migrations or when substantial redesign is required.

2. Automated Migration Tools

Informatica provides automated migration utilities that convert PowerCenter objects to IICS. This is ideal for large-scale migrations with minimal changes to existing workflows.

3. Hybrid Approach

The hybrid approach to the manual and automated methods help businesses to leverage the strengths of both. This is suitable when some parts of the ETL logic require redesign, while others can be directly migrated.

Step-by-Step Data Migration Guide

Step 1: Migration Assessment and Planning

Objective: Evaluate the current PowerCenter environment and plan the migration strategy.

1. Inventory Analysis
  • Identify all the objects in PowerCenter such as mappings, sessions, workflows, and transformations.
  • Categorize them based on their complexity and criticality.
2. Feasibility Study
  • Determine the compatibility of PowerCenter objects with IICS.
  • Identify potential challenges and constraints in the migration process.
3. Resource Planning
  • Allocate resources for the migration project, including team members, tools, and infrastructure.
  • Set timelines and milestones for the migration process.
4. Backup and Documentation
  • Take a complete backup of the PowerCenter environment.
  • Document all existing processes, configurations, and dependencies.
Step 2: Environment Setup

Objective: Prepare the IICS environment for migration.

1. Provision IICS Services
  • Set up the IICS environment with necessary services and configurations.
  • Ensure network connectivity and security settings are in place.
2. Data Integration Service Configuration
  • Configure connections to source and target systems.
  • Set up user roles and permissions.
Step 3: Object Migration

Objective: Migrate PowerCenter objects to IICS.

1. Using Automated Tools
  • Utilize Informatica's migration tools to convert mappings, workflows, and other objects to IICS format.
  • Validate the converted objects for correctness and completeness.
2. Manual Rebuilding
  • Recreate complex mappings and workflows in IICS using the available components.
  • Optimize the design to leverage IICS capabilities.
3. Hybrid Approach
  • Migrate simpler objects using automated tools.
  • Manually rebuild or redesign complex objects that require optimization.
Step 4: Data Migration Testing and Validation

Objective: Ensure the migrated objects function correctly in the IICS environment.

1. Unit Testing
  • Test individual mappings and workflows to ensure they produce the expected results.
  • Validate data transformations and logic.
2. Integration Testing
  • Testing the end-to-end data integration process for smooth integration of the different elements.
  • Validating the data flow from source to target systems for holistic testing approach.
3. Performance Testing
  • Measure the performance of the migrated workflows in IICS.
  • Identify and address any performance bottlenecks.
Step 5: Process of Data Migration and Reconciliation

Objective: It covers the migration of the data from the source systems to the target systems while ensuring data integrity.

1. Initial Data Load
  • Perform an initial data load from the source systems to the target systems using IICS.
  • Validate the data load process for accuracy and completeness.
2. Data Reconciliation
  • Comparison between the data of the source and target systems to ensure consistency.
  • Resolving any possible data issues identified during the reconciliation process.
Step 6: Go-Live and Post-Migration Support

Objective: Transition to the new IICS environment and provide ongoing support.

1. Go-Live Preparation
  • Plan the cutover activities and schedule downtime if necessary.
  • Communicate the migration plan to all stakeholders.
2. Go-Live Execution
  • Perform the final data load and switch over to the IICS environment.
  • Monitor the system closely during the initial phase to ensure stability.
3. Post-Migration Support
  • Provide support to address any issues that arise after the migration.
  • Monitor the performance and optimize as necessary.

Measures to Take Before Migration

1. Comprehensive Assessment
  • Conduct a thorough assessment of the existing PowerCenter environment.
  • Identify all dependencies, customizations, and integrations.
2. Stakeholder Engagement
  • All the required stakeholders participate in the planning process.
  • Ensure clear communication and alignment on the migration strategy.
3. Training and Education
  • Train the migration team on IICS features and best practices.
  • Provide end-user training to ensure a smooth transition.
4. Data Quality and Governance
  • Implement data quality checks and governance policies.
  • Ensure data integrity and consistency throughout the migration process.
5. Risk Management
  • Identification of the possible mitigation risks and develop mitigation strategies.
  • Preparation of a contingency plan to handle any upcoming issues.
