Before creating a real-time synchronization task in DataArts Migration, you must check the items listed in the following table to ensure that the environment meets the requirements of the task.

**Table 1** Check items
Item	Description	Preparation
Account and permissions of Huawei Cloud	Prepare a HUAWEI ID. Create a user and authorize the user to use DataArts Migration.	See Registering a Huawei ID and Enabling Huawei Cloud Services. See Authorizing the Use of Real-Time Data Migration.
Real-time computing resource group	You need to buy the compute resources required by the real-time migration task and associate them with the DataArts Studio workspaces you want to use.	See Buying a DataArts Migration Resource Group Incremental Package. See Associating a Real-Time Migration Resource Group with Workspaces.
Databases	Prepare the source and destination databases and the corresponding connection account permissions. NOTE: You are advised to create an independent database account for the connection of the migration task to prevent task failures caused by account modification. After changing the account passwords for the source or destination databases, modify the connection information in the migration task as soon as possible to prevent automatic retry after a task failure. Automatic retries will lock the database accounts.	The required permissions vary depending on the link and database. For details, see Tutorials.
Connections	Create data connections in DataArts Studio Management Center. NOTE: When creating a data connection, you must select DataArts Migration for Applicable Modules. The agent used in a data connection is a CDM cluster. You are advised to upgrade the cluster to version 24.4.0B030 or a later version to meet function and feature requirements. For details, contact the customer service or technical support.	For details, see Configuring DataArts Studio Data Connection Parameters.
Network	Databases are deployed in an on-premises IDC.	Prepare the network by referring to Database Deployed in an On-premises IDC.
	Databases are deployed on another cloud.	Prepare the network by referring to Database Deployed on Another Cloud.
	Databases are deployed on Huawei Cloud.	Prepare the network by referring to Database Deployed on Huawei Cloud.
