Driving subscriber migration at scale - from legacy systems to next-gen platforms.

Over a five-year period, VEON Group, one of the world’s largest telecom operators, undertook a bold transformation initiative: migrating mobile and broadband subscribers across six diverse markets to a unified, modern BSS architecture.

The Scope:

The program spanned:

  • Georgia
  • Algeria
  • Bangladesh
  • Kyrgyzstan
  • Ukraine
  • Pakistan

 

Each market presented unique regulatory, technical, and operational challenges. The goal: consolidate fragmented legacy systems into a future-ready stack built on:

  • Ericsson Charging System (ECS)
  • Qvantel Digital BSS

Our Role:

TDMC staff played a strategic and technical leadership role across multiple phases of the program:
  • Migration Strategy & Planning
    Defined tailored migration strategies for each market, balancing global consistency with local customization.
  • Legacy-to-Target Mapping
    Conducted deep-dive analyses of legacy platforms, aligning subscriber data, charging logic, and service configurations with ECS and Qvantel capabilities.
  • Execution & Governance
    Led cross-functional teams through design, testing, and cutover, ensuring data integrity, service continuity, and stakeholder alignment.
  • Multi-Market Coordination
    Navigated complex geopolitical and regulatory landscapes, adapting delivery models to suit each country’s telecom environment.

The Outcome:

  • Millions of subscribers successfully migrated across six countries including 80 million customers in a single night.
  • Standardized BSS architecture enabling faster product launches and simplified operations
  • Improved billing accuracy and customer experience
  • Future-proofed infrastructure for digital growth and innovation
