How to change cloud computer specifications-Elastic Desktop Service-阿里云帮助中心

Background

Resizing a cloud computer only affects its computing resources. This operation does not impact its storage resources or user data. Because the prices of the original and new specifications may differ, resizing can result in additional charges or a refund.

The limitations for different types of resize operations are as follows:

Billing method	Resize type	Limitations
All	All	Only cloud desktops of the same specification type support mutual configuration changes，that is, office-type specifications and graphics-type specifications cannot be changed between each other。 Only supports changing from one cloud desktop specification to another cloud desktop specification，you cannot individually modify configurations within a cloud desktop specification。 For the same cloud desktop，the interval between two configuration change operations must not be less than5minutes。
Monthly subscription (unlimited hours)	Upgrade	You must pay the price difference for the remainder of the current billing cycle. If you have renewed your subscription or performed a downgrade within the current billing cycle, you cannot upgrade the cloud computer until the next billing cycle begins. To convert a monthly subscription (unlimited hours) to one with a compute package, see Convert Billing Plan for Monthly Hour Package.
Monthly subscription (unlimited hours)	Downgrade	You can downgrade the specifications of a cloud computer a maximum of three times per month. Once this limit is reached, you cannot perform another downgrade until the quota is automatically reset on the first day of the next month. The refund is calculated using the following formula: `Refund Amount = Remaining Duration × (Price Difference between Old and New Specifications / Total Duration)`. The actual refund amount is shown on the user interface. Refunds are issued to the original payment method. Used coupons are not refunded. Note In this formula, Remaining Duration is the active subscription time left before the downgrade, and Price Difference is the cost difference between the original and new specifications.
Monthly subscription with compute package	All	Changes to the specifications of a cloud computer with a monthly subscription with compute package are implemented by unsubscribing from the current cloud computer and purchasing a new one. This results in a refund for the current subscription and a new pending payment for the new subscription. You cannot directly downgrade this type of cloud computer. To downgrade, first back up important data to prevent data loss, unsubscribe from the current cloud computer, and then purchase a cloud computer with lower specifications. The unsubscribed cloud computer is released. To convert a subscription with a compute package to one with unlimited hours, see Convert Monthly Hour-based Billing Plan.

FAQ

Does resizing affect data, installed software, or custom images?

Resizing is an in-place configuration change that adjusts only compute resources. It does not affect user data, installed software, or custom images, so you do not need to reinstall the operating system or applications.

To reduce the impact of unexpected events, create a snapshot or custom image backup before resizing. After a downgrade, confirm that the new specifications provide enough resources for your current software workloads. Insufficient resources can prevent software from running normally.

How long does resizing take? Can I cancel it or use the console during the process?

Resizing typically takes 10 to 15 minutes. You cannot stop or cancel a resize after it starts, so wait for the operation to complete.

During resizing, the cloud computer is locked and the console restart and power controls are unavailable. This is normal. Do not force operations because doing so can damage data. If the status remains Changing Specifications for an extended period, refresh the page to confirm the actual status. If the status does not change after you refresh the page, investigate the issue further.

What should I do if resizing reports incompatible specifications or insufficient inventory (`InvalidDesktopType.SoldOut`)?

If the specifications are incompatible, check the following compatibility requirements: the target specifications must belong to the same specification family as the source cloud computer, use the same CPU architecture (x86 or ARM), and match the boot mode, such as UEFI. For Windows cloud computers, also verify that the target specifications meet the required CPU core and memory requirements.

The InvalidDesktopType.SoldOut error code indicates that the current resource pool has insufficient inventory. Wait and try again later, or select another available specification.

I purchased a new cloud computer instead of resizing the original one. How do I move the configuration or data back?

You cannot directly transfer the configuration or billing plan of a newly purchased cloud computer to the original cloud computer. Refund the newly purchased cloud computer, and then resize the original cloud computer.

If you must use the new cloud computer, create a custom image from the original cloud computer and use that image to restore data on the new cloud computer.

Prerequisites

The cloud computer must be in the Stopped state. If the cloud computer is not stopped when you start resizing, the system automatically stops it. This terminates running processes and can cause unsaved data loss. Save your work, create a snapshot backup, and schedule the resize during an off-peak period before proceeding. For instructions, see Start, Stop, Restart, or Release Cloud Computers.
Before you resize a cloud computer, ensure that it has no pending orders. Otherwise, the operation may fail. If there are pending orders, in the top navigation bar of the console, click Price. In the left-side navigation pane of the Expenses and Costs page, click Orders > My Orders. Then, pay for or cancel the pending orders.

Resize a single cloud computer

Log on to the EDS enterprise console.
In the left-side navigation pane, choose Resources > Cloud Computers.
In the top navigation bar, select a region.
On the Cloud Computers page, find the target cloud computer and, in the Actions column, click More > Change Type.
In the Change Configurations panel, perform one of the following operations based on the billing method:
- For a pay-as-you-go cloud computer, select the target specifications and click Change.
- For a monthly subscription (unlimited hours) cloud computer, select the target specifications on the Upgrade Configurations or Downgrade tab and click Change.
- For a monthly subscription cloud computer with a compute package, select the target specifications, a compute package, and a subscription duration, and then click OK.
The panel displays any additional charges or refund amounts at the bottom. During the resize process, the cloud computer's status changes to Changing Specifications on the Cloud Computers page.

Resize multiple cloud computers

In the left-side navigation pane, choose Resources > Cloud Computers.
In the top navigation bar, select a region.
On the Cloud Computer Enterprise Edition page, select multiple cloud computers that are in the Stopped state, and at the bottom of the cloud computer list, click More>Change Type.

Note
You can resize up to 100 cloud computers at once.
In the Change Configurations panel, in the Filter Cloud Computer section, select the cloud computers that you want to resize, and click Next.

Note
You can only resize multiple cloud computers at once if they have the same billing method. If you select cloud computers with different billing methods, you must filter them by billing method and resize each group separately.
In the Change Configurations panel, perform one of the following operations based on the billing method:
- For a pay-as-you-go cloud computer, select the target specifications and click Change.
- For a monthly subscription (unlimited hours) cloud computer, select the target specifications on the Upgrade Configurations or Downgrade tab and click Change.
- For a monthly subscription cloud computer with a compute package, select the target specifications, a compute package, and a subscription duration, and then click OK.
The panel displays any additional charges or refund amounts at the bottom. During the resize process, the cloud computer's status changes to Changing Specifications on the Cloud Computers page.
