Table 1 SMS limitations

Item

Description

Server specifications

  • Windows: Source and target servers must have more than 1 CPU and 1 GB memory.
  • Linux: Source and target servers must have at least 1 CPU and 1 GB memory.

Source server quantity

A maximum of 1,000 source servers are allowed per account. Delete the migrated servers from the server list in a timely manner so that other servers can continue to be migrated.

OSs

Available disk space

  • Windows
    • At least 320 MB available space on a partition not smaller than 600 MB
    • At least 40 MB available space on a partition smaller than 600 MB
  • Linux

    At least 200 MB of available space on the root partition

File systems

  • Windows: Only NTFS file systems are supported.
  • Linux: Only Ext2, Ext3, Ext4, VFAT, XFS, and Btrfs file systems are supported.

Shared file systems

SMS cannot migrate files from shared file systems such as NFS or CIFS, or from NAS devices.

External storage of servers

SMS cannot migrate data from the external storage attached to a source server.

Encrypted files

SMS cannot migrate OSs that contain protected folders or encrypted volumes.

Servers running multi-node databases and Active Directory Domain Services (AD DS)

SMS cannot migrate servers that host active directories or multi-node databases.

Data of database applications and domain controller applications

SMS cannot migrate data of database applications and domain controller applications.

Applications bound to hardware

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

Dynamic disks

Dynamic disks in Windows systems are migrated as basic disks. After the migration is complete, the target server will not have dynamic disks.

Servers added to a domain

After migrating servers added to a domain, you need to add them to the domain again.

Servers with system volumes located on disks other than the first disk

SMS cannot migrate servers whose system volumes are not on the first disk.

Thinly-provisioned volumes

SMS cannot migrate thinly-provisioned volumes.

Servers with RAID arrays

SMS cannot migrate servers with RAID arrays.

Big data clusters and container clusters

SMS cannot migrate clusters including but not limited to container clusters and big data clusters.

Supported OSs

The OSs of servers to be migrated must be supported by SMS. For details, see Supported Windows OSs, Table 3 and Table 4.

If you need to migrate a source server that runs an OS not supported by SMS, there are several ways to do this:

The following tables list the OSs supported by SMS.
