关于迁移About migration

阅读此文快速了解 Azure Site Recovery 服务如何帮助迁移计算机。Read this article for a quick overview of how the Azure Site Recovery service helps you to migrate machines.

下面是可以使用 Site Recovery 迁移的内容:Here's what you can migrate using Site Recovery:

  • 从本地迁移到 Azure:将本地 Hyper-V VM、VMware VM 和物理服务器迁移到 Azure。Migrate from on-premises to Azure: Migrate on-premises Hyper-V VMs, VMware VMs, and physical servers to Azure. 迁移之后,在本地计算机上运行的工作负荷将在 Azure VM 上运行。After the migration, workloads running on the on-premises machines will be running on Azure VMs.
  • 在 Azure 中迁移:在 Azure 区域之间迁移 Azure VM。Migrate within Azure: Migrate Azure VMs between Azure regions.
  • 迁移 AWS:将 AWS Windows 实例迁移到 Azure IaaS VM。Migrate AWS: Migrate AWS Windows instances to Azure IaaS VMs.

迁移的意思是什么?What do we mean by migration?

除了可以使用 Site Recovery 对本地和 Azure VM 进行灾难恢复外,还可以使用 Site Recovery 服务迁移这些 VM。In addition to using Site Recovery for disaster recovery of on-premises and Azure VMs, you can use the Site Recovery service to migrate them. 区别是什么?What's the difference?

  • 对于灾难恢复,定期将计算机复制到 Azure。For disaster recovery, you replicate machines on a regular basis to Azure. 发生服务中断时,将从主站点将计算机故障转移到辅助 Azure 站点,并从该处对其进行访问。When an outage occurs, you fail the machines over from the primary site to the secondary Azure site, and access them from there. 当主站点再次可用时,可从 Azure 进行故障回复。When the primary site is available again, you fail back from Azure.
  • 对于迁移,将本地计算机复制到 Azure 或将 Azure VM 复制到辅助区域。For migration, you replicate on-premises machines to Azure, or Azure VMs to a secondary region. 然后可将 VM 从主站点故障转移到辅助站点,并完成迁移过程。Then you fail the VM over from the primary site to the secondary, and complete the migration process. 不涉及故障回复。There's no failback involved.

迁移方案Migration scenarios

方案Scenario 详细信息Details
从本地迁移到 AzureMigrate from on-premises to Azure 可将本地 VMware VM、Hyper-V VM 和物理服务器迁移到 Azure。You can migrate on-premises VMware VMs, Hyper-V VMs, and physical servers to Azure. 为此,完成的步骤几乎与完整灾难恢复的步骤一样。To do this, you complete almost the same steps as you would for full disaster recovery. 只是不会将计算机从 Azure 故障回复到本地站点。You simply don't fail machines back from Azure to the on-premises site.
在 Azure 区域之间迁移Migrate between Azure regions 可将 Azure VM 从一个 Azure 区域迁移到另一个 Azure 区域。You can migrate Azure VMs from one Azure region to another. 迁移完成后,现在可以在迁移到的次要区域中为 Azure VM 配置灾难恢复。After the migration is complete, you can configure disaster recovery for the Azure VMs now in the secondary region to which you migrated.
将 AWS 迁移到 AzureMigrate AWS to Azure 可将 AWS 实例迁移到 Azure VM。You can migrate AWS instances to Azure VMs. Site Recovery 将 AWS 实例视为用于迁移目的的物理服务器。Site Recovery treats AWS instances as physical servers for migration purposes.
