Can I Migrate an ECS to Another Region, AZ, or Account?

From x86 physical servers to Huawei Cloud servers

For example, P2V

The servers can access the Internet.

Server Migration Service

For details, see Best Practices - Server Migration Service.

None

From VMs (such as VMware) on a virtualization platform to Huawei Cloud servers

The VMs can access the Internet.

Server Migration Service

For details, see Best Practices - Server Migration Service.

None

The VMs cannot access the Internet.

1. Export the VM image files from the VMware virtualization platform.
2. Import the image files to Huawei Cloud.

If the image file format is not vhd, vmdk, qcow2, raw, vhdx, qcow, vdi, qed, zvhd, or zvhd2, convert the file format.

Between cloud servers on Huawei Cloud (across accounts, regions, or AZs)

For example, migrating the cloud servers of account A in the CN North-Beijing4 region to account B in the CN East-Shanghai1 region

The cloud servers can access the Internet.

Server Migration Service

For details, see Best Practices - Server Migration Service.

None

The cloud servers cannot access the Internet.

Recommended

• Migration across accounts: Sharing Images.

  Use the source cloud server's system disk to create a system disk image and the data disk to create a data disk image, or use the source cloud server to create a full-server image. Then, share the images with other accounts.

• Migration across regions: Replicating images across regions.

  Use the source cloud server's system disk to create a system disk image and the data disk to create a data disk image, or use the source cloud server to create a full-server image. Then, replicate the images to other regions.

• Migration across accounts and regions: Sharing Images and Replicating Images Across Regions.
• Migration across AZs: Creating an ECS from an Image.

  Use the source cloud server's system disk to create a system disk image and the data disk to create a data disk image, or use the source cloud server to create a full-server image. Then, use the Apply for Server function of the image to create a cloud server in the target AZ.

Only the full-server images created using CBR can be shared.

The size of images to be replicated across regions cannot be greater than 128 GiB.

From a third-party cloud platform to Huawei Cloud

For example, from Alibaba Cloud or Tencent Cloud to Huawei Cloud

The cloud servers can access the Internet.

Server Migration Service

None

The cloud servers cannot access the Internet.

1. Export the image from the source cloud platform.
2. Import the image files to Huawei Cloud.

If the image file format is not vhd, vmdk, qcow2, raw, vhdx, qcow, vdi, qed, zvhd, or zvhd2, convert the file format.

Installation disk imaging

For example, create an image file offline and import it to Huawei Cloud.

The ISO installation disk image of the required OS is available.

Create a Windows image using VirtualBox and upload the image to Huawei Cloud.

Or

Create an image using an ISO file imported to Huawei Cloud.
