Before you use Server Migration Center (SMC) to migrate an operating system, 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.
Endpoints and ports
During the migration process, make sure that the network connections among the source server, the intermediate instance, and the SMC endpoint are normal.
Make sure that the source server can access the following endpoints:
If the information about the migration source is automatically imported by using the console or the migration source is activated by using an activation code, one of the following endpoints is used:
Default public endpoint: https://smc-service.aliyuncs.com.
Internal endpoint: https://<region-id>.axt.aliyun.com. Only Elastic Compute Service (ECS) instances can access the internal endpoint.
If the information about the migration source is manually imported by using the SMC client and the migration source is activated by using an AccessKey pair, one of the following endpoints is used:
Default public endpoint: https://smc.aliyuncs.com. The IP addresses of the servers are 101.37.132.1 and 47.111.202.72.
Internal endpoint: https://smc.vpc-proxy.aliyuncs.com. Only ECS instances can access the internal endpoint.
NoteBy default, all SMC endpoints use HTTPS port 443. HTTP port 80 may not be supported.
