Before you use Server Migration Center (SMC) to perform migration, you must create an Alibaba Cloud account, add funds to the account, and complete the real-name verification.
- On the Alibaba Cloud official website, create an Alibaba Cloud account.
- Associate a credit card or PayPal account with your Alibaba Cloud account.
For more information, see Add a payment method.
- Before you migrate servers to mainland China, complete the real-name verification.
- Make sure that Resource Access Management (RAM) is activated and SMC is authorized
to access your cloud resources.
Use one of the following methods to authorize SMC:
RAM user authorization: Use your Alibaba Cloud account to log on to the RAM console, and grant the AliyunSMCFullAccess permission to the RAM user.
- Create the AccessKey pair for your Alibaba Cloud account or RAM user and obtain the
AccessKey pair. For more information, see Create an AccessKey pair.
Notice AccessKey pairs are credentials that you can use to access Alibaba Cloud API resources. Therefore, we recommend that you keep your AccessKey pair strictly confidential. We recommend that you use a RAM user to create a temporary AccessKey pair and then disable the AccessKey pair after the migration is complete. This prevents the AccessKey pair from being leaked or misused.
- Make sure that the snapshot service is activated. For more information, see Activate ECS Snapshot.
- Do not perform operations on the intermediate instance.
To run a migration task, SMC creates a temporary intermediate instance named
No_Delete_SMC_Transition_Instancefor your Alibaba Cloud account. For more information, see What are the specifications available for intermediate instances? Do not stop, restart, or release the intermediate instance during a migration task. Otherwise, the migration task fails. After the migration is complete, the intermediate instance is released.
- By default, the following data directories are migrated:
- For Windows servers: Only data on the C drive (including shared directories that are attached to the C drive) is migrated as a partition of the system disk. If you need to migrate the data from other partitions such as the D drive, you must select and configure the data disk when you create a migration task. For more information, see Migration task parameters.
- For Linux servers: Data in all subdirectories (including shared subdirectories) in the root directory is migrated as a partition of the system disk. If you need to migrate the data in other directories such as /disk1, you must select and configure the data disk when you create a migration task. For more information, see Migration task parameters. If you do not need to migrate the data of multiple directories, see (Optional) Exclude files or directories from migration.
