Yes, the CVM can change the system, but replacing the system is a high-risk operation. Be sure to read the notes given by the service provider carefully before replacing the system disk. For example, the risks of changing a CVM to a system include:

1. The original system disk will be released. It is recommended to create a snapshot in advance to back up the data.

two。 Replacing the system disk requires stopping the instance, which will disrupt the business of the website.

3. After the replacement is completed, the business operating environment needs to be redeployed in the new system disk, which may cause a long-term interruption to the business.

Replacing the system disk is equivalent to reassigning a system disk to the CVM instance, and the disk ID will change, so the snapshot created based on the old system disk cannot be used to roll back the new system disk.

Matters needing attention in changing the CVM to the system

1. Cross-operating system replacement refers to the mutual replacement of Windows and Linux systems. The file system format of the data disk may not be recognized.

two。 If your data disk does not have important data, it is recommended to reinitialize the data disk and format it to the default file system of the corresponding system.

3. If there is important data on the data disk, if the Windows system is replaced by a Linux system or the Linux system is replaced by a Windows system, a separate software identification is required.

At present, Windows system only supports password authentication, while Linux system can support both password authentication and SSH key authentication. The above is an introduction to whether the CVM can change the system.
