Upgrading a FlexusL Instance

Scenarios

If the vCPUs, memory, system disk capacity, peak bandwidth, or data package of your FlexusL instance cannot meet your service requirements, you can upgrade the instance.

When you upgrade a FlexusL instance, the vCPUs, memory, system disk capacity, peak bandwidth, and data package packed into the instance are upgraded together to new specifications not lower than the current ones. For example, the following upgrade is not supported because the target peak bandwidth and data package are lower than the current ones.

Constraints

• Resources (vCPUs, memory, data package, peak bandwidth, and system disk capacity) included in a FlexusL instance cannot be upgraded separately. They must be upgraded together.
• Instance specifications can only be upgraded, not downgraded. Upgraded instance specifications cannot be downgraded either.

Billing

When upgrading specifications, you need to pay the difference in price. For details, see Pricing of a Changed Specification.

Preparations

An upgrade failure may result in lost server data. You are advised to back up the data using CBR before you continue. For details, see Method 2: Manual Backup.
