Online migration supports migrating or synchronizing systems and applications on the source server or virtual machine from your IDCs or other cloud platforms to Tencent Cloud with no system downtime. With go2tencentcloud, the migration tool provided by Tencent Cloud, you can directly migrate all systems and applications on the source server to the destination CVM, without the need to create, upload, and import images. It can meet enterprises' business requirements for cloud deployment, cross-cloud migration, cross-account or cross-region migration, and hybrid cloud deployment.
Note:
The source server can be a physical server, a virtual machine, or a cloud server on third-party cloud platform, such as AWS, Google Cloud Platform, VMware, Alibaba Cloud, or Huawei Cloud.

Differences from Offline Migration

In offline migration, you need to create images for system disks or data disks on source servers, and then migrate images to the Cloud Virtual Machine (CVM) or Cloud Block Storage (CBS). You do not need to create images for online migration. Instead, you can run the migration tool on source servers to migrate them to destination CVMs.
