Migrating from Informatica PowerCenter to Informatica Intelligent Cloud Services (IICS) is a strategic move to leverage the advanced capabilities and scalability of the cloud platform. This migration involves careful planning and execution to ensure a smooth transition without disrupting business operations.

This blog post provides a detailed, step-by-step guide on how to perform the migration and the ways it can be done. Not to miss are the measures that need to be taken before the migration.

Discover a detailed guide on migrating from Informatica PowerCenter to IICS. Learn the steps involved, key considerations, and how this move enhances scalability and performance.

Introduction to migration from Informatica PowerCenter to IICS

Migrating from an on-premises ETL tool like Informatica PowerCenter to a cloud-based solution such as IICS can bring numerous benefits. It covers the improved scalability, enhanced performance, and reduced infrastructure costs.

However, the migration process requires thorough planning and careful execution to ensure a seamless transition. This guide will walk you through the entire process, offering insights into different migration strategies and best practices.

Migration Strategies

Some of the top strategies for migrating from Informatica PowerCenter to Informatica Intelligent Cloud Services (IICS) covers:

  • 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.
  • 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.
  • Hybrid approach
    Combining manual and automated methods allows you 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 Migration Guide

The different steps involved in the process of migrating from Informatica PowerCenter to Informatica Intelligent Cloud Services (IICS) refers to:

  • Step 1: Assessment and planning of the current PowerCenter environment Objective: Evaluate the current PowerCenter environment and plan the migration strategy.

Sub step 1- Inventory analysis

  • Identify all the objects in PowerCenter such as mappings, sessions, workflows, and transformations.
  • Categorize them based on their complexity and criticality.

Sub step 2- Feasibility study

  • Determine the compatibility of PowerCenter objects with IICS.
  • Identify potential challenges and constraints in the migration process.

Sub step 3- Resource planning

  • Allocate resources for the migration project, including team members, tools, and infrastructure.
  • Set timelines and milestones for the migration process.

Sub step 4- Backup and documentation

  • Take a complete backup of the PowerCenter environment.
  • Document all existing processes, configurations, and dependencies.
  • Step 2: IICS environment setup
    Objective: Prepare the IICS environment for migration.

Sub step 1- Provision IICS services

  • Set up the IICS environment with necessary services and configurations.
  • Ensure network connectivity and security settings are in place.

Sub step 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.

Sub step 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.

Sub step 2- Manual rebuilding

  • Recreate complex mappings and workflows in IICS using the available components.
  • Optimize the design to leverage IICS capabilities.

Sub step 3- Hybrid approach

  • Migrate simpler objects using automated tools.
  • Manually rebuild or redesign complex objects that require optimization.
  • Step 4: Testing and validation
    Objective: Ensure the migrated objects function correctly in the IICS environment.

Sub step 1- Unit testing

  • Test individual mappings and workflows to ensure they produce the expected results.
  • Validate data transformations and logic.

Sub step 2- Integration testing

  • Test the end-to-end data integration process to ensure all components work together seamlessly.
  • Validate data flow from source to target systems.

Sub step 3- Performance testing

  • Measure the performance of the migrated workflows in IICS.
  • Identify and address any performance bottlenecks.
  • Step 5: Data migration and reconciliation
    Objective: Migrate data from the source systems to the target systems and ensure data integrity.

Sub step 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.

Sub step 2- Data reconciliation

  • Compare data between the source and target systems to ensure consistency.
  • Resolve any data discrepancies identified during the reconciliation process.
  • Step 6: Go-live and post-migration support
    Objective: Transition to the new IICS environment and provide ongoing support.

Sub step 1- Go-live preparation

  • Plan the cutover activities and schedule downtime if necessary
  • Communicate the migration plan to all stakeholders.

Sub step 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.

Sub step 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

Before moving ahead with the migration, it is essential to take care of the following points:

1. Comprehensive assessment

  • Conduct a thorough assessment of the existing PowerCenter environment.
  • Identify all dependencies, customizations, and integrations.

2. Stakeholder engagement

  • Involve all relevant stakeholders 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

  • Identify potential risks and develop mitigation strategies.
  • Prepare a contingency plan to handle any unforeseen issues.
