    NTT DATA is well suited for governed cutover execution where discovery, schema and data mapping, and controlled cutover planning must be paired with measurable data quality validation. Wipro and Globant fit when phased migrations require governance-led planning and stabilization support across multi-source landscapes.

Common Mistakes to Avoid

Most failures in cloud data migration programs come from mismatched delivery scope, weak validation discipline, and reliance on late-stage client decisioning that delays design and cutover.

  • Starting cutover planning without rollback and risk-controlled release runbooks

    Capgemini reduces release risk by using documented cutover and rollback runbooks, while Wipro uses wave-based cutover planning paired with structured validation. Providers that focus only on migration execution without controlled release artifacts can create higher downtime risk during complex cutovers.

  • Treating governance and validation as optional rather than delivery gates

    Accenture, Deloitte, and PwC build governance controls and validation testing into the delivery model so mapping correctness is verified before go-live. Infosys and NTT DATA also include governance and data quality validation checkpoints to prevent inaccurate data from reaching downstream analytics.

  • Underestimating the schedule coordination required for multi-system and multi-platform migrations

    Accenture and IBM Consulting deliver coordination across multiple systems using migration factory or target architecture planning, but complex multi-platform scope still requires tight stakeholder alignment.
