If your current Edge Security Acceleration (ESA) plan does not meet your needs, you can upgrade to a plan with more quotas and features.
Scenarios
Consider a plan upgrade in the following scenarios:
Exceeded traffic usage: The monthly traffic of your website often exceeds the plan limit, incurring 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.
In the above cases, choose the plan that best fits your needs.
Upgrade rules
The following diagram shows the plans offered by ESA.
Plan upgrade: You can upgrade from a lower-tier plan to a higher-tier one. Plan downgrade is not supported.
Pay the price difference: The new plan inherits the remaining validity time of the original one. 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.

Billing rules for a plan upgrade
When you upgrade a plan, the upgrade fee is calculated based on the price difference of your new plan and your original one.
Billing formula
Payment = (New plan price - Original plan price) × Remaining validity period of the original plan × Discount for the remaining validity period
Payment: The value is accurate to USD 0.01.
Plan price: The plan price on the ESA official website or console.
Remaining validity period of the original plan: The new plan inherits the remaining validity period of your original plan. The period is calculated in hours and then converted into months based on a 30-day monthly cycle.
Discount for the remaining validity period: If you are eligible for a discount for your original plan, you can use the discount for the remaining validity period.
Traffic quota
After the purchase is complete, your plan quotas are automatically upgraded.
The following rules apply to your traffic quota:
Traffic is calculated by calendar month.
Traffic is measured in gigabytes (GB). The value is rounded up to the nearest integer.
Traffic is converted as follows: 1 GB = 1,000 MB, 1 TB = 1,000 GB, and so on.
The traffic quota after upgrade is calculated as followed:
If you have used up the traffic in your original plan, ESA allocates to you the quota difference between the new and original plans.
Calculation rules for the current month after a plan upgrade
Formula:
Traffic quota this month after the upgrade = Remaining 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 / Total hours this month
Traffic quota this month after the upgrade: The value calculated based on the formula.
Remaining traffic quota this month in the original plan: Traffic quota unused = Monthly traffic quota in the original plan × Remaining hours this month/Total hours this month.
Monthly traffic quota in the new plan: The monthly traffic quota of your new plan displayed on the ESA official website or console.
Monthly traffic quota in the original plan: The monthly traffic quota of your original plan displayed on the ESA official website or console.
Remaining hours this month: The hours left in the current month.
Total hours this month: The total hours in the current month.
