Upgrade

Billed fees = Total fees of the new configuration for the remaining subscription duration (Unit price of the new configuration × Remaining subscription duration) - Total fees of the original configurations for the remaining subscription duration (Unit price of the original configuration × Remaining subscription duration).

Example: The original configurations of the instance contain two LindormTable nodes each with 4 CPU cores and 16 GB of memory. The new configurations of the instance contain two LindormTable nodes each with 8 CPU cores and 16 GB of memory. The monthly price of the original configuration is USD 185.76. The monthly price of the new configuration is USD 312.63. The remaining subscription duration is 50 days. The fees for the configuration changes can be calculated by using the following formula: (312.63/30 × 50) - (185.76/30 × 50) = USD 211.45.

FAQs

Why are the fees displayed on the configuration change page different from the fees displayed on the page a few days earlier?

Fees incurred for the configuration changes of a subscription instance depend on the remaining subscription duration of the instance and the difference between the original and new configurations.

The remaining subscription duration of an instance changes every day. Therefore, fees displayed on the upgrade page vary upon days.

You can check the expiration time of the instance on the configuration change page to calculate the remaining subscription duration of the instance.

Example: A subscription instance contains two LindormTable nodes each with 4 CPU cores, 16 GB of memory, and 480 GB of storage capacity. The monthly price for the instance is USD 185.76. You want to upgrade the LindormTable nodes to a specification that contains 8 CPU cores and 16 GB of memory. If the remaining subscription duration of the instance is 10 days, the fees incurred by the upgrade can be calculated by using the following formula: (312.63/30 × 10) - (185.76/30 × 10) = USD 42.29. If the remaining subscription duration of the instance is 5 days, the fees incurred by the upgrade can be calculated by using the following formula: (312.63/30 × 5) - (185.76/30 × 5) = USD 21.145.
