You can convert an existing NAT service plan to an EIP bandwidth plan. EIP bandwidth plans support bandwidth sharing and transferring on a regional scale. After you purchase an EIP bandwidth plan, you can add all elastic IP addresses (EIPs) in the same region to the EIP bandwidth plan. This saves bandwidth costs because these EIPs can share the bandwidth of the EIP bandwidth plan.
Considerations
- The public IP addresses in the NAT service plan are converted to EIPs.
- The NAT service plan is converted to an EIP bandwidth plan, which is easier to manage and more cost-effective.
- If the conversion fails, you can continue to use the NAT service plan. If you fail
to locate the cause of the conversion failure, submit a ticket. When you submit a ticket, you must provide the following information:
- Your account ID (UID).
- The request ID generated by Alibaba Cloud when you call the ConvertBandwidthPackage operation.
- The ID of the NAT service plan that failed to be converted.
- The screenshot of the conversion failure.
Preparations
Before you convert a NAT service plan, make sure that the following requirements are met:
- Your account has the permissions to convert the NAT service plan.
We recommend that you use your Alibaba Cloud account to convert the NAT service plan. If you want to convert the NAT service plan as a Resource Access Management (RAM) user, you must first log on to the RAM console with your Alibaba Cloud account and grant the RAM user the following permissions:
- AliyunNATGatewayFullAccess
- AliyunEIPFullAccess
- AliyunCommonBandwidthPackageFullAccess
- Your account has sufficient unused EIPs.
After the NAT service plan is converted, the public IP addresses in the NAT service plan are converted to EIPs. Make sure that the number of EIPs is greater than or equal to the number of public IP addresses in the NAT service plan. In the Virtual Private Cloud (VPC) console, you can view the number of EIPs on the Quota Management page. If the number of EIPs is insufficient, you can apply for more in the VPC console.
- Your account is in the whitelist if the NAT service plan is charged on a pay-by-data-transfer
basis.
If the NAT service plan to be converted is billed on a pay-by-data-transfer basis, submit a ticket to apply for the permissions to convert the NAT service plan.
- The information about the NAT service plan is backed up.
Before you convert your NAT service plan, fill the following table with the NAT service plan information, so that you can track the conversion progress and verify the result.

Procedure
After the prerequisites are met, perform the following operations to start the conversion:
