Learn about the supported instance type changes before you modify your instance type.

Supported source and destination instance types

When changing an instance type, you can change from the following source instance types to destination instance types:

Note

You can also call the API operation DescribeResourcesModification to query the supported changes for existing instances.

Possible limitations and solutions

When changing an instance type, the following unsupported scenarios may occur. You can resolve these issues based on your specific situation before proceeding with the change.

Fix the source instance in advance

When changing an instance type, if you receive one of the following error messages, you can fix the source instance yourself and then change the instance type.

Reason

Description

Solution

Reason

Description

Solution

The processor of the destination instance type is incompatible with the operating system of the current instance

Some ECS instance types have limitations on the supported operating systems. For example:

If the operating system used by the source instance does not match the destination instance type, the change is not supported.

For more information, see The operating system of the image and the processor of the instance type are not officially compatible.

The NVMe drive status of the destination instance type does not match that of the current instance

If the selected destination instance supports NVMe, the source instance must also support NVMe. Otherwise, the change is not supported.

Note

You can query whether an instance type supports NVMe by using the NvmeSupport field in the API operation DescribeInstanceTypes.

  1. In the row of the source instance in the list, select image > Set Nvme Drive Status.

  2. Click One-click Installation to install the NVMe driver. The system automatically changes the NVMe drive status to Installed.

image

The destination instance type does not support the disk type of the current instance

Some instance families support only specific disk types. For example, g7, general-purpose instance family supports only ESSD disks. If the source instance has disks of types that are not supported by the destination instance type, the source instance cannot be changed to the destination instance type. For example, if the source instance has ultra disks attached, it cannot be changed to an instance type that supports only ESSD disks.

You can change the disk types of the source instance at the same time when you change the instance type, as prompted on the interface.

image

Change the destination instance type

When changing an instance type, if you receive one of the following error messages, you must change the destination instance type.

Reason

Description

Solution

Reason

Description

Solution

The instance type does not exist

The destination instance type that you selected does not exist.

Select another destination instance type.

Note

Before you change the source instance type, check Available instance families.

The instance type is offline

The destination instance type that you selected is offline.

Select another destination instance type.

Note

Before you change the source instance type, check Available instance families.

No inventory in the region

The destination instance type that you selected has no inventory in the current region.

Select another destination instance type.

Note

You can go to Instance Types Available for Purchase to query the available instance types in the current region and zone. You can also call the API operation DescribeResourcesModification to query the inventory of instance types in a zone.

Only changes within the same instance family are supported

When you change these instance types, you can select only instance types within the same instance family.

The destination instance type must be within the same instance family as the source instance. For example, when you change a gn7e instance type, you can select only instance types within the gn7e instance family, not instance types within other families.

The destination instance family does not match the source instance family

If the selected destination instance type does not match the source instance type, the change is not supported.

For more information, see Supported source and destination instance types. Select a destination instance type that matches the source instance family.

The architecture of the destination instance type does not match that of the source instance

If the architecture (ARM or x86) of the selected destination instance does not match that of the source instance, the change is not supported.

The destination instance type must have the same architecture as the source instance.

The number of CPU cores or memory size of the destination instance type is not within the supported range

If the number of CPU cores or memory size of the selected destination instance does not match that of the source instance, the change is not supported. For example, for information about the limitations of Windows operating systems on the number of CPU cores and memory size of instances, see Memory Limits for Windows and Windows Server Releases.

The destination instance type must have a matching number of CPU cores or memory size as the source instance.

The boot mode of the destination instance type does not match that of the current instance

For example, if the selected destination instance is a security-enhanced instance type that supports only the UEFI boot mode, the source instance must also support the UEFI boot mode. Otherwise, the change is not supported.

The destination instance type must have the same boot mode as the source instance.

Instance types that do not support changes

The instance types within the following instance families do not support changes. Therefore, you cannot change the instance type of the current instance.
