Before you use Server Migration Center (SMC) to migrate an Elastic Compute Service (ECS) instance across zones, you must create an Alibaba Cloud account, complete real-name verification, activate the Resource Access Management (RAM) service, and authorize SMC to access your cloud resources.
Create an Alibaba Cloud account
To create an Alibaba Cloud account, perform the following steps:
On the Alibaba Cloud official website, create an Alibaba Cloud account.
Associate a credit card or PayPal account with your Alibaba Cloud account.
If you want to migrate the server to a region in the Chinese mainland, you must complete real-name verification.
You can use one of the following methods to complete real-name verification:
Method 1: Go to the Account Verification page.
Method 2: Log on to the SMC console and complete real-name verification as prompted.
Activate RAM and authorize SMC to access your cloud resources
Before you use SMC to migrate servers, you must authorize SMC to access your cloud resources. In this case, make sure that you have activated RAM and authorized SMC to access your cloud resources. You can log on to the SMC console and complete the authorization as prompted.
If you use SMC as a RAM user, you must log on to the RAM console by using your Alibaba Cloud account and then attach the
AliyunSMCFullAccesspolicy to the RAM user.
Activate the snapshot service.
Snapshots are created for the source server during migration. Make sure that you have activated the snapshot service. You can log on to the SMC console and activate the snapshot service as prompted.
Back up data
To prevent data loss or damage due to factors such as system failure, you must create snapshots to back up data.
