What Information Does SMS Collect About Source Servers?
SMS uses the Agent to collect source server details to evaluate the migration feasibility and provide data required for selecting or configuring target servers. Table 1 lists the data collected from a Windows server. Table 2 lists the data collected from a Linux server. All collected data is used for migration only.

Usage |
---|---|---|
Environment information |
OS version |
Used for migration feasibility check. Only source servers with OSs included in Table 2 can be migrated. |
Firmware type |
Used for migration feasibility check. The source server can be booted from BIOS or UEFI. |
|
CPU |
Used for recommending the target server flavor. |
|
Memory |
Used for recommending the target server flavor. |
|
System directory |
Used for configuring the target server. After the migration is complete, it will be used to restore the registry. |
|
Disk partition style |
Used for configuring the target server. Before the migration, the disks of the target server must be formatted to be the same as those of the source server. |
|
File system |
Used for migration feasibility check. Only the NTFS partitions can be migrated. |
|
Available space |
Used for migration feasibility check. If there is not enough space on a source server partition, the migration may fail. |
|
OEM system check |
Used for migration feasibility check. If the system is an OEM system, the OS needs to be reactivated after the migration. |
|
Driver files |
Used for migration feasibility check. The source server must have basic disk drivers. |
|
System services |
Used for migration feasibility check. Volume Shadow Copy Service (VSS) must be available on the source server. |
|
User permissions |
Used for migration feasibility check. You must have the administrator permissions to run the Agent. |
|
Disk information |
|
Used for checking whether the disk specifications of the target server meet the migration requirements. |

Environment information |
OS version |
Used for migration feasibility check. Only servers with OSs included in Table 3 or Table 4 can be migrated. |
CPU |
Used for recommending the target server flavor. |
|
Memory |
Used for recommending the target server flavor. |
|
Paravirtualization |
Used for migration feasibility check. SMS does not support migration of paravirtualized source servers. |
|
Firmware type |
Used for migration feasibility check. The source server can be booted from BIOS or UEFI. |
|
Boot mode |
Used for migration feasibility check. The source server must be booted from BIOS. |
|
rsync |
Used for evaluating synchronization feasibility. SMS synchronization depends on rsync on the source server. |
|
Raw device |
Used for migration feasibility check. The source servers to be migrated cannot contain raw devices. |
|
Disk partition |
Used for migration feasibility check. The source disk partition style must be Main Boot Record (MBR) or GUID Partition Table (GPT). |
|
Disk partition style |
Used for configuring the target server. Before the migration, the disks of the target server must be formatted to match the source server. |
|
File system |
Used for migration feasibility check. The file systems on the source server must be Ext2, Ext3, Ext4, VFAT, XFS, or Btrfs. |
|
Disk information |
|
Used for checking whether the disk specifications of the target server meet the requirements. |
