System Changes After Migration

{{ $t('productDocDetail.updateTime') }}: 2025-12-22

The system configuration will also change accordingly since the physical or virtual machine's operating platform has changed after the migration. The specific changes are shown in the following table.

Category

Details

CPU

The total number of CPU cores is the same as the source machine by default.

The total number of CPU cores can be changed. The minimum number of cores is 1.


Memory/RAM

The memory size is the same as the source machine by default.

The memory size can be changed, and the changed memory cannot be less than 2G.

Disk

After the Windows dynamic disk is migrated, it becomes a basic disk.

The disk driver may be changed after the migration (virtio driver is used by default).

The disk partition size will change after the migration (when the remaining disk space is less than 1G, the remaining space will be automatically allocated to the last partition).

Disks that are not in GPT and MBR format will be converted to GPT or MBR format.

When the system disk is not the first disk, it will be automatically adjusted as the first disk.

Network

Configuration

Virtio driver will be used by default for Windows2003 and above.

Linux kernel 2.6.18-128 and above use virtio (For other kernel versions, ide+e1000 will be used).

The MAC and IP of the network card will be changed (consistent with the migration task switching parameters).

System

configuration changes

The UUID of the OS changes and applications that rely on the UUID of the system need to be re-authorized, such as Windows license,  EDR license, etc.

Performance optimization   tools(vmTools)

According to HCI rules, performance optimization tools will be installed on the following OS:

1. Windows 2003 and above

2. Linux 2.6.18-128 and above.
