Usage Overview
You can use Huawei Cloud EulerOS in the following ways:
- Select a HCE public image when creating an ECS.
- Change the OS to HCE.
If only the ECS OS needs to be changed but the other ECS details (NICs, disks, and VPNs) need to be kept the same, as long as the software is loosely coupled to the OS, you can change the OS to HCE with only a few additional changes needed.
- Migrate the OS to HCE.
If you want to change the ECS OS but retain other details (NICs, disks, and VPNs) and the OS component parameter settings, you can migrate the OS to HCE.
NOTE:
The OS can be migrated only to Huawei Cloud EulerOS 2.0 Standard Edition or Huawei Cloud EulerOS 1.1 CentOS-compatible Edition.
