Customer problem
The legacy Exasol Data Platform is encountering significant challenges:
-
Inefficient Total Cost of Ownership (TCO): The platform's inefficiency negatively impacts the company’s financial health.
-
Aging Technology: The outdated infrastructure creates operational disruptions, hindering smooth and efficient business processes.
-
Lack of Cloud Innovation: The platform’s inability to integrate cloud technologies blocks potential opportunities for business growth and improvement.
-
Non-competitive Business Strategy: Reliance on an outdated data platform hampers the company’s agility and slows market expansion.
Migrating from Exasol to AWS Redshift presents inherent risks due to hidden dependencies and unpredictable complexities. Without a well-structured strategy, these risks can lead to inefficient migration processes and potential failures.
EPAM Solution
The EPAM Migration & Modernization offering is structured into two primary components:
-
Exasol Assessment: This component is an automated examination of the existing Exasol Data Platform. By utilizing leading-edge automation technologies, it scrutinizes the Data Warehouse systems, Lua scripts, ETL mechanisms, and reporting to pinpoint migration challenges, establish the best scale for migration, and formulate an AI-guided strategy for migration aimed at minimizing both duration and expense.
-
Exasol Migration to AWS Redshift: With the aid of artificial intelligence, this stage oversees the transfer, enhancement, and restructuring of the outdated data systems. It integrates EPAM's established methodologies, covering automated translation of Exasol codes, reconciliation of data, assistance during the cutover phase, and managing expenses, all to facilitate a frictionless changeover with heightened automation and preserved data integrity.

Problem Statement
The client launched a large-scale program to modernize the Fast Serving Layer for its critical reporting systems, MicroStrategy and Tableau.
To improve performance and scalability, they planned a migration from Exasol to AWS Redshift.
Though intended as a re-platforming to AWS Redshift and conversion from Exasol and Lua, it required a deep understanding of data structures, object relationships, and reports, along with maximum automation for a smooth transition.
Solution Proposed
- Evaluation and Transition Planning: EPAM used migVisor to assess Exasol and related platforms, mapping architecture, data relationships, and workloads. This defined the target architecture and migration strategy.
- Target Architecture & Migration Strategy: Based on migVisor insights, EPAM designed a target architecture for Redshift and the Data Lake and created a migration plan focusing on workload prioritization and dependency management.
- Migration Execution: Exasol workloads were migrated to Redshift using migVisor Converter, automating the transformation logic. BI reports were redirected to Redshift, and data replication ensured continuous synchronization between Redshift and the Data Lake.
- Post-Migration Validation: migVisor Reconciler validated data accuracy, and a detailed migration runbook outlined the process, timelines, and roles for a successful release.
Achieved Results
In the migration from Exasol to AWS Redshift we successfully:
- Transferred 10,000 data objects
- Converted 1,200 Lua scripts
- Adjusted 50,000 reporting objects
Our AI tools identified duplicates, optimized data mesh domains, and defined independent migration streams, cutting migration costs by 50%. The LLM-powered Code Converter boosted code conversion by 40%, while the Reconciler minimized manual reconciliation efforts.
Questions & Answers
What approach does EPAM take for modernizing Exasol systems?
EPAM's Exasol modernization strategies include:
- Full Upgrade to AWS Redshift: This method builds a scalable, secure architecture with advanced cloud analytics, including cloud-native and Lua scripting capabilities to foster growth and innovation.
- Initial Migration with Optional Enhancement: This faster, cost-effective approach begins by moving Exasol workloads to AWS Redshift with the possibility of later enhancements. This strategy offers immediate benefits and cost reductions, allowing businesses to gradually integrate more sophisticated cloud services.
Each strategy has its benefits: the full upgrade ensures a robust, future-proof system, while the initial migration focuses on speed and cost savings. The migration involves a detailed examination and transfer of data, including transforming logic and Lua scripts, ensuring a smooth transition to cloud-native features with minimized risk and optimized costs.
How does EPAM implement its Exasol modernization process?
EPAM's Exasol modernization to AWS Redshift follows a six-phase process. It starts by assessing the Exasol environment, defining the migration scope, and identifying dependencies. Next, a detailed plan is crafted, followed by testing strategies with a pilot. The full-scale migration is then executed, including data migration and code conversion. Post-migration support is provided to optimize AWS Redshift performance. Finally, improvements are made based on results, ensuring a smooth transition and ongoing optimization.
What sets EPAM's Exasol Migration apart in the market?
EPAM sets itself apart in Exasol migration with its innovative migVisor product suite, tailored to streamline and expedite transitions to AWS Redshift. The suite, equipped with sophisticated tools for assessment, conversion, and testing, efficiently analyzes the Exasol ecosystem, automates the conversion of SQL and Lua scripts, and rigorously tests the migrated data.
This automation reduces manual labor, lowers risks, and quickens the overall migration timeframe, facilitating a smooth switch to AWS Redshift.
