What to Look for When Choosing a Cloud Migration Service Provider?

A reliable cloud migration provider should demonstrate relevant platform expertise, secure delivery methods, industry experience, transparent governance, realistic cost planning, business-continuity controls, and the ability to optimize and support the environment after migration.

• Platform expertise: Confirm that the provider has proven experience with the platforms in your environment, such as Microsoft Azure,
  AWS, Google Cloud, Microsoft 365, SharePoint, Oracle, SAP, or hybrid infrastructure.
• Assessment and discovery:
  The provider should inventory applications, data, dependencies, integrations, identity, permissions, compliance obligations, and technical debt before proposing a migration schedule.
• Relevant project experience:
  Look for case studies involving similar data volumes, technologies, regulations, operational constraints, and business outcomes.
• Security and compliance:
  Evaluate encryption, identity, access control, data residency, backup, retention, auditing, regulatory requirements, and incident-response practices.
• Migration methodology: A
  strong approach includes discovery, architecture, pilot testing, phased execution, validation, rollback planning, cutover management, and stabilization.
• Cost transparency: Request a
  clear breakdown of consulting, migration tools, licenses, cloud consumption, data transfer, remediation, user adoption, and ongoing support.
• Business continuity: The migration plan should minimize disruption, define acceptable downtime, and protect critical integrations
  and user access throughout the transition.
• Governance and optimization:
  The provider should establish monitoring, cost controls, lifecycle policies, security baselines, ownership, and operational standards for the new environment.
• Post-migration support:
  Confirm who will resolve issues after go-live and whether documentation, training, knowledge transfer, adoption, and managed services are included.

For organizations centered on Microsoft technologies, Reality Tech offers a particularly strong combination of Microsoft 365, SharePoint, Azure, Exchange Online, Power Platform, and Purview expertise.
