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.

**Table 1** Collected Windows server details
Item	Sub-Item	Usage
Environment information	OS version	Used for migration feasibility checks. Only source servers with OSs included in Supported Windows OSs 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	Disk name Disk partition style Disk size Used space	Used for checking whether the disk specifications of the target server meet the migration requirements.

**Table 2** Collected Linux server details
Item	Sub-Item	Usage
Environment information	OS version	Used for migration feasibility checks. Only source servers with OSs included in Supported Linux OSs 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 be the same as those of 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	Disk name Disk partition style Disk size Used space	Used for checking whether the disk specifications of the target server meet the requirements.
