Migrating workloads without a validated baseline creates technical and financial risk that compounds after go-live. Dependencies between applications, misconfigured access controls, and workloads untested in the target environment generate remediation costs that often exceed what the migration cost to execute.
Your compliance posture is equally at risk without structured planning. Regulatory frameworks including HIPAA, PCI-DSS, and ISO 27001 impose requirements on how data is stored, accessed, and protected in cloud environments, and gaps that existed before migration will follow your workloads unless addressed before the move.
