Overview
You can merge multiple reserved instances into a single reserved instance with a larger normalization factor, so as to apply it to larger on-demand instances. Rules and Limits
The original reserved instances are in the Activated status.
The original reserved instances are in the same availability zone.
The payment methods for the original reserved instances are the same.
The original reserved instances have the same operating system (Windows/Linux) and expiration time.
Merging the 1C1G, 1C2G, and 2C4G reserved instances is not supported.
You can modify the instance size but not the instance family.
Modifying the region or availability zone of a reserved instance is not supported.
The total normalization factors of destination reserved instances must be equal to that of the original reserved instance.
Make sure the CPU:MEM ratio is the same before merging.
Directions
1. Log in to the CVM console.
2. Click Reserved Instances in the left sidebar.
3. On the Reserved Instances page, find the original reserved instances and click Merge under the Operation column.
4. In the pop-up window, select the reserved instances to be merged, and enter a new name for the destination reserved instance.
Execution Result
After merging, the original reserved instances enter the Expired status, while the new reserved instance is in Activated status.
Definitions
Normalization factor: It indicates the CPU performance of an instance. For the splitting and merging of reserved instances, the normalization factor is calculated based on the number of vCPUs.
Sum of normalization factor = Normalization factor of the instance size × Instance quantity. The sum of normalization factors must keep the same as the one before splitting.
