GB1004F Migration Assurance Guidebook v1.0.0

This paper is designed to provide comprehensive, high-level guidelines that help Communication Service Providers (CSPs) understand the complexities of migrating their operational and business support systems. The key focus of the paper is to clarify the role and scope of the migration assurance team, outlining how this team operates and what responsibilities it holds in ensuring a smooth transition. It also identifies the primary challenges that CSPs commonly face during migration, including potential risks related to data integrity, system outages, billing discrepancies, and customer service disruptions.

To assist CSPs in effectively managing these risks, the paper will propose several risk mitigation strategies. These strategies will be aligned with industry’s leading practices and tailored to address both the technical and operational complexities that accompany large-scale system migrations.
