If your Edge Security Acceleration (ESA) plan in use does not meet your needs, you can upgrade it to one that offers more quotas and functionalities.
Scenarios
You may consider a plan upgrade in the following scenarios:
Exceeded traffic usage: The monthly traffic of your website often exceeds the plan limit, which incurs additional charges for extra traffic usage.
Insufficient rule quota: You need to configure more rules such as caching and configuration rules to adapt to diverse scenarios. However, this demand cannot be fulfilled by your current plan.
Higher security requirements: Your origin frequently faces DDoS attacks or intrusion attempts, which indicates that the protection level or policies offered by the existing plan are inadequate.
Other feature requirements: You want to add subdomains to ESA, or require security analytics or expert services.
You can choose a new plan that best fits your needs by referring to Compare plans.
Upgrade rules
The following diagram shows the different plans offered by ESA.
Only plan upgrade is supported.
Plan downgrade is not supported.
The new plan inherits the validity period of the original plan. In an upgrade, you only need to pay for the price difference between the two plans for the remaining duration. For more information, see Billing rules for a plan upgrade.
Prerequisites
The plan that you want to upgrade is in the In Effect state. An expired plan cannot be upgraded directly and must be renewed before an upgrade. For information about the status of plans, see Query plan information.
Procedure
Log on to the ESA console.
In the left-side navigation pane, choose .
On the Plans page, find the plan that you want to upgrade and click Upgrade in the Actions column.
In the Upgrade Plan dialog box, select the plan to which you want to upgrade, select the check box to confirm that you have read and agree to the service level agreement, and then click OK.

Billing rules for a plan upgrade
If you upgrade a plan, ESA calculates the price difference between the original plan and the new plan. Then, you only need to pay for the price difference. After the upgrade completes, you can use the features and functionalities offered by the new plan.
Billing description
Calculation rules
Formula:
Price difference = (New plan price - Original plan price) × Remaining duration × Discount for the remaining duration
Price difference: the price difference between the two plans, with the value rounded down to two decimal places.
Plan price: the plan price on the ESA official website.
Remaining duration: ESA first calculates how many hours are left until the expiration time of the original plan from the purchase time of the new plan. The calculated number of hours is then converted into months based on a 30-day monthly cycle.
Discount for the remaining duration: If you are eligible for discounts, fees are deducted based on the discount.
Quota description
Traffic quota
The following rules apply in a plan upgrade:
Traffic is calculated by calendar month.
Traffic is measured in GB. The value is rounded up to the nearest integer.
Traffic is converted in the following ways: 1 GB = 1,000 MB, 1 TB = 1,000 GB, and so on.
After you upgrade your plan, the traffic quota for the current month will be adjusted based on the following rules.
ImportantIf you upgrade a plan during a month, the traffic quota for this month is calculated by using a formula. If you have used up the quota of the original plan before the upgrade, the system calculates the difference between the quotas of the new and original plans. You will be allocated with the quota difference for this month.
For the rest of the months in the plan's validity period, the traffic quota is calculated based on the number of valid hours in the month and the monthly quota offered by the new plan.
Rules of calculating the traffic quota for the current month after a plan upgrade
Formula:
Traffic quota this month after the upgrade = Available traffic quota this month in the original plan + (Monthly traffic quota in the new plan - Monthly traffic quota in the original plan) × Remaining hours this month for the new plan/Total hours this month for the new plan
Traffic quota this month after the upgrade: the actual traffic quota you can use in this month after an upgrade. The value is rounded up to the nearest integer.
Available traffic quota this month in the original plan = Monthly traffic quota in the original plan × Remaining hours this month/Total hours this month.
Monthly traffic quota in the new plan: the total monthly traffic quota in the new plan that is displayed on the ESA official website.
Monthly traffic quota in the original plan: the total monthly traffic quota in the original plan that is displayed on the ESA official website.
Remaining hours this month for the new plan: the number of remaining valid hours in the current calendar month for the new plan.
Total hours this month for the new plan: the total number of hours in the current calendar month for the new plan.
Example
User A purchased a 3-month Entrance plan (50 GB/month) at 15:15:49 on March 11, 2024. The plan is valid until 00:00:00 on June 12, 2024. Due to increasing business requirements, User A upgraded the plan to Pro (500 GB/month) at 18:25:42 on March 28, 2024. The following table describes the traffic quota provided to User A each month in the validity period.
Month | Original traffic quota | New traffic quota after the upgrade |
March | 32 GB | 32 GB + 48 GB |
April | 50 GB | 500 GB |
May | 50 GB | 500 GB |
June | 19 GB | 184 GB |
Calculation details
New traffic quota in March:
Available traffic quota this month in the original plan: 50 GB/month × [(March 31 - March 12) × 24 hours + (24:00:00 - 15:00:00)]/(31 days × 24 hours) = 31.25 GB. The value is then rounded up to 32 GB.
Monthly traffic quota in the new plan: 500 GB/month.
Monthly traffic quota in the original plan: 50 GB/month.
Remaining hours this month for the new plan: (March 31 - March 28) × 24 hours + (24:00:00 - 18:00:00)= 78 hours.
Total hours this month for the new plan: 31 days × 24 hours= 744 hours.
Traffic quota this month after the upgrade: 32 GB + (500 GB/month - 50 GB/month) × 78 hours/744 hours= 79.1774 GB. The value is then rounded up to 80 GB.
Therefore, the final traffic quota of User A in March is 80 GB.
New traffic quota in April: 500 GB, as the monthly traffic quota prescribed in the Pro plan.
New traffic quota in May: 500 GB, as the monthly traffic quota prescribed in the Pro plan.
New traffic quota in June:
Monthly traffic quota in the new plan: 500 GB/month.
Remaining hours this month for the new plan: (June 12 - June 1) × 24 hours = 264 hours.
Total hours this month for the new plan: 30 days × 24 hours= 720 hours.
Available traffic quota this month: 500 GB/month × 264 hours/720 hours = 183.3333 GB. The value is then rounded up to 184 GB.
Therefore, the final traffic quota of User A in June is 184 GB.
Other benefits
After the upgrade completes, you can seamlessly use the features and functionalities offered by the new plan.
