Server Migration
The overall server migration is a migration requirement that remains unchanged from the entire virtual machine level. Generally, there are two situations as follows:
Migrate to another Region in same Cloud
Just need to create image for your Server and copy image to new region, then create new Server for it.
Migrate to another Cloud
Migrate to another Cloud need these steps:
- 针对目标云平台的要求,在待迁移的虚拟机上安装一系列所需的软件:Cloud-Init, virtio 驱动等
- 基于虚拟机创建镜像
- 将镜像导出为一个文件(格式:vhd, RAW 等)
- 将导出的文件上传到目标云平台的对象存储空间中
- 基于对象存储已上传的文件,创建云上的镜像
- 基于云上的镜像创建虚拟机
