Product IntroductionConstraints and Limitations

Constraints and Limitations

  • The system disk should be <=1000G, data disk should be <=8000G, and keep more than 500M available space (please contact technical support if Linux exceeded)
  • USMC does not migrate memory data, so it is impossible to migrate memory database products such as Redis
  • When there are MySQL/PostgreSQL/MongoDB/TiDB services, it is recommended to use UDTS to migrate the database first, or to migrate after terminating the service/business
  • USMC does not migrate the hostname. If the machine contains services that depend on the hostname such as RabbitMQ/K8S, please handle it by yourself
  • Does not support migration of Linux machines that include disk array RAID and LVM volumes
  • If the machine contains shared file systems, such as NFS, NAS, it is recommended to uninstall it first and then start the migration
  • Please ensure that the directories has enough read permissions for Linux migration, and try to use the root user to execute the agent
  • After migration, the MAC/IP/SID of the server may change, causing the application license to become invalid, please solve it by yourself
