The risk of cloud migration is not limited to resource switching. It also includes data integrity, business validation, and security operations. For platforms that support public-service capabilities, the migration plan should define validation methods for databases, Redis, ES, and other critical data objects before execution, while including personal information protection, data desensitization, access control, and vulnerability checks in the same acceptance scope.
The Shanghai Parking cloud migration and data security case shows that migration projects need to cover both technical migration and security design. The acceptance conclusion in the project materials emphasizes that all data was completely migrated and business validation passed, which means migration success should not be judged only by whether services start successfully.
When planning cloud migration, enterprises can first clarify four questions: which data must be fully validated, which business processes require regression validation, which permission and desensitization policies must go live together, and who will be responsible for monitoring, alerting, backup, and recovery after launch.
