When selecting ETL tools for migration, consider both immediate migration needs and ongoing data integration requirements. The correct solution should support the initial data transfer and the continued synchronization of data across systems during phased implementations.

Upgrading Capabilities with Data Visualization Tools

Migration creates an opportunity to upgrade your data visualization tools and reporting capabilities. Modern cloud-based visualization platforms offer significant advantages over legacy reporting systems:

  1. Interactive, self-service dashboards
  2. Advanced visualization types and customization options
  3. Embedded analytics capabilities
  4. Mobile-friendly design
  5. Artificial intelligence-powered insights

When implementing new visualization tools, carefully analyze user requirements and report dependencies. Plan for a transition period during which users can access legacy reports and new visualizations to reduce disruption to business operations.

Adding Self-Service Business Intelligence Capabilities
