Constraints
- Migration is only supported for public images for ECSs listed in the Supported Instance Types.

- The remaining OS memory should be greater than 128 MB, the remaining system disk space (required for running the migration tool) be greater than 5 GB, and the available space of the boot partition be greater than 200 MB.
- The name of a customized RPM package must be different from that of the OS RPM package. Otherwise, the custom RPM package will be deleted by the migration tool during the migration.
- After the OS migration, the system disk type cannot be changed.
- During OS migration, certain conflicting packages are generated in the system to be migrated. They will be automatically deleted after the OS migration. For details about the conflicting packages, see Conflicting Packages.
