Challenge

The data migration posed not only a technical challenge but was also critical from a business perspective. During the project, we had to ensure that all relevant customer and transaction data was accurately and completely transferred to the new system while adhering to all regulatory requirements and data protection standards.

In designing the data transfer process, we conducted a thorough analysis of both banks' data structures. This included mapping out Sberbank’s existing systems, identifying data types and formats, and conducting an in-depth review of MBH’s database. Special attention was given to ensuring compliance with data protection regulations and safeguarding customer data throughout the process.

How we helped?

  • Data Transfer Process Design
  • During the design of the data transfer process, we performed a detailed analysis of both banks' data structures. This process included data cleansing, transformation, and validation.
  • Identification of Data Sources
  • We mapped and categorized relevant data stored in Sberbank’s systems.
  • Historical Data Management
  • Handling historical data was a particularly sensitive task during the project. These data were crucial for the bank's long-term operations, regulatory compliance, and the preservation of customer histories.
  • Development of Mappings and Specifications
  • The creation of mappings and specifications was key to successful data migration. This process involved a detailed analysis of both Sberbank's and MBH's systems, comparing data structures and formats, and identifying necessary transformations. We collaborated closely with both IT and business teams throughout this phase.
  • Managing Data Quality Challenges
  • We faced various challenges, including inconsistent data formats, incomplete records, and outdated information. To address these issues, we developed a comprehensive data cleansing and correction strategy.
  • Development and Implementation of Loading Jobs
  • The jobs were designed to efficiently process large volumes of data while ensuring data integrity and traceability throughout the process.
  • Temporary Data Extraction Process
  • During the critical transition period, we established a temporary data extraction process to ensure compliance with monthly and annual closing requirements. This solution enabled continuous business operations and accurate financial reporting during the interim phase.
