Migration Assurance
Subex embeds business assurance expertise at every stage, validating data completeness, charging accuracy, and UAT coverage so issues are caught in test, not in the live network. It is the best of both worlds: proven technology paired with hands-on services and consulting. Migrate with confidence, not crossed fingers.
What prevented us in the past?
- Legacy migrations are high-risk due to complex, tightly coupled, and poorly documented billing, charging, and data systems.
- Even small transfer gaps can lead to revenue leakage, billing inaccuracies, and service disruptions.
- If rating and charging rules, or subscribers and customer accounts don’t migrate correctly: - Subscriptions and usage may be under-billed - Discounts may be misapplied.
- Post-migration impact often includes: - Heavy rework and manual reconciliation - Integration fixes and operational firefighting.
- Compliance and regulatory data gaps can expose the business to penalties.
- These challenges ultimately increase budgets (either CAPEX or OPEX), delay timelines, squeeze margins, and damage customer trust and brand credibility.
How Subex Helps
- Define the migration strategy for every stage: before migration, during migration and post migration
- We strengthen UAT and BCT/RCT by validating coverage of high-risk business assurance scenarios, from partner settlements to bundled product lifecycles. Our proprietary risk library helps ensure no critical revenue-impacting process is overlooked before go-live.
- Our framework validates risks across the entire Business Assurance ecosystem, connecting migration testing with Mobile Money, 5G & Network Assurance, and Partnership Management. This ensures migrations don't introduce fraud risks, disrupt partner settlements, or create downstream business impacts.
- Validate the completeness, correctness and accuracy of the migration
- Subex performs comprehensive quality assurance through data validation and system functionality checks at every stage. By integrating revenue controls, margin analysis, and operational risk assessments, we ensure migrations are technically sound and financially optimized.

Frequently Asked Questions
Everything you need to know about how our Migration Assurance solutions work.
What are the key risks during a telecom BSS/OSS migration?
Legacy migrations are high-risk because systems are complex, tightly coupled, and poorly documented. Even small transfer gaps can cause revenue leakage, billing inaccuracies, and service disruptions. If rating and charging rules or subscriber accounts do not migrate correctly, subscriptions may be under-billed or discounts misapplied. Compliance gaps can expose the business to penalties, and post-migration issues often include heavy rework, manual reconciliation, increased costs, delayed timelines, and damage to customer trust.
How does Subex structure its Migration Assurance service across phases?
Subex embeds Business Assurance domain expertise directly into UAT, BCT, and RCT phases, validating test scenarios against a proprietary risk library to ensure no critical revenue-impacting process is overlooked. The framework operates across three phases: pre-migration (strategy validation, readiness checks), during migration (configuration and go-live validations), and post-migration (updated risk control matrix, SOPs, customer experience validation, and system integration checks).
