Online migration is a server migration method that supports migrating or synchronizing systems and applications on the source server or virtual machine from a self-built IDC or other cloud platforms to Tencent Cloud with no operating system downtime on the source server.
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.
Use Cases
Online migration is applicable to the scenarios including but not limited to:
Cloud migration from self-built IDCs
Migration across cloud vendors
Migration from simple application servers to Cloud Virtual Machine (CVM)
Cloud migration from local virtual machines
Hybrid cloud architecture deployment
Migration across accounts, regions, or AZs
Differences from Offline Migration
For offline migration, you need to first create an image of the system disk or data disk on the source server and then migrate the image to a specified CVM instance or cloud disk. For online migration, you do not need to create an image. Instead, you can directly run the migration tool on the source server to migrate its data to a specified CVM instance or a custom image.
Starting Migration
Two methods for online migration are available. You can select the appropriate one as needed.
|
| Log in to the source server, run the migration tool go2tencentcloud, import the migration source, create a migration task in the console, and complete the migration. | Migrate via the public and private network Migrate from other cloud platforms to Tencent Cloud Migrate from customer IDC to Tencent Cloud | High compatibility. More migration parameters can be specified to meet different migration needs. |
| Log in to the console, perform identity authentication, quickly import the migration source and create a migration task. | No need to log in to the source server Migration via the public network Cross-cloud migration: Applicable to the scenarios where the source instances are located in Alibaba Cloud | One-stop batch migration. |
