What Source Server OSs Are Supported by SMS and Are There Any Restrictions on Using SMS?

For details about the source server OSs supported by SMS, see Supported Windows OSs, Table 2.

If you need to migrate a source server whose OS is not supported by SMS, use any of the following methods:

  • Use Image Management Service (IMS) to create an image for the source system disk from an external image file.
  • Use a public image from IMS to create ECSs and deploy server applications on the newly created ECSs. With this method, there is actually no server migration involved.

  • Migration constraints and limitations
    Table 3 Constraints and limitations on source servers

    Source Server Type

    Description

    OS

    Available disk space
    • Windows: at least 320 MB of available space on a partition not smaller than 600 MB; at least 40 MB of available space on a partition smaller than 600 MB
    • Linux: at least 200 MB of available space on the root partition

    File system
    • Windows: Only NTFS partitions are supported.
    • Linux: Only ext2, ext3, ext4, VFAT, XFS, and Btrfs file systems are supported.

    Shared file system

    Only files on the local disk can be migrated. Files in the shared file systems, such as NFS and CIFS file systems, cannot be migrated.

    Encrypted file

    OSs that contain protected folders and encrypted volumes cannot be migrated.

    Database and Active Directory Domain (AD DS) application

    SMS does not support AD and multi-node database migration.

    Applications bound to hardware

    SMS does not support the migration of OSs that contain applications bound to hardware.

    Dynamic disk

    In Windows, dynamic disks are migrated as basic disks. After the migration is complete, the target ECS will not have dynamic disks.

    Servers added to a domain

    If you want to migrate a server added to a domain, after the migration is complete, the target ECS must be added to that domain.
