Online Discovery

Prerequisites

• You have installed the MgC Agent in the source intranet environment and have connected it to MgC.
• You have added source server credentials to the MgC Agent. The server credentials must meet the following requirements:
  • Linux: root and its password
  • Windows: administrator and its password

Procedure

1. Sign in to the MgC console. In the navigation pane, under Project, select your application migration project from the drop-down list.
2. In the navigation pane, choose Discover > Source Resources.
3. Under Online Discovery, click Cloud Discovery.

4. Configure the parameters listed in Table 1 to create a discovery task.

   Table 1 Parameters for creating a cloud discovery task

   Area	Parameter	Description	Mandatory
   Basic Settings	Task Name	Enter a task name.	Yes
   	Task Description	Describe the task.	No
   Task Settings	Source Platform	Select the source cloud platform. Currently, Alibaba Cloud, Huawei Cloud, AWS, Tencent Cloud, Azure, Qiniu Cloud, and Kingsoft Cloud are supported.	Yes
   	Credential	Select the credential for accessing the source cloud platform. If no credential is available, choose Create to add one. For details, see Managing Credentials. If the source cloud platform is Alibaba Cloud, Huawei Cloud, AWS, Tencent Cloud, Qiniu Cloud, or Kingsoft Cloud, select AK/SK for Authentication and enter the AK/SK pair of your source cloud account. If the source cloud platform is Azure, Select ID/Secret for Authentication. To learn how to obtain Azure credentials, see How Do I Obtain Azure Credentials?	Yes
   	Region	Select the region where your source environment is located. Multiple regions can be selected.	Yes
   	Resource Type	Select Servers from the drop-down list.	Yes
   	Application	Select the application that you want to group the discovered servers into. If no applications are available, perform the following steps to create one: Click Create Application, enter an application name and description, select a business scenario and running environment, and select the region where the application resources will be deployed on the target cloud. Click OK.	No

5. Click Confirm. The Internet-based discovery task is created, and MgC starts collecting details about source servers.
6. Wait until the task status changes to Succeeded. Then perform the following steps to check the migration readiness for the discovered source servers.
   1. Install the MgC Agent in the source intranet environment and connect the MgC Agent to MgC.
   2. Go to the Source Resources page, in the server list, select the servers to be migrated and click Group as Application above the list. If you have specified an application in the Internet-based discovery task for discovering these source servers, skip this step.
      • If you have created an application, select the application from the drop-down list and click OK.
      • If you have not created an application, click Create Application in the displayed dialog box. Then enter an application name and description, select a business scenario, environment, and target region, and click Create. Then click OK.
   3. On the top of the server list, choose Migration Scenario > Server migration.
   4. For each source server, click Configure in the Migration Readiness column.
   5. Configure the parameters listed in Table 2.

      Table 2 Parameters for configuring migration readiness

      Parameter	Configuration
      Type	Set this parameter based on the source server OS type.
      MgC Agent	Select the MgC Agent installed in the source environment.
      Access IP Address	Select the IP address for accessing the source server. It can be a public or private IP address. After the pre-migration check is passed, the IP address you select here will be used for migration.
      Port	Enter the port on the source server that allows access from the MgC Agent. By default, port 5985 on Windows source servers must be opened to the MgC Agent. The port cannot be changed. By default, port 22 on Linux source servers must be opened to the MgC Agent. You can specify a different port if needed.
      Credential	Select the server credential. If the credential is not displayed in the list, go to the MgC Agent console, add the server credential, and synchronize it to MgC. NOTICE: The account provided in the credential must have sufficient permissions, so the MgC Agent can collect necessary server details. To perform a deep collection for the server to collect as much as details, the credential you provided must meet the following requirements: Linux: root and its password Windows: administrator and its password

   6. Click Confirm. The system checks whether the source server can be accessed using the information you provided and whether the server can be migrated. If Ready shows up in the Migration Readiness column, the source server can be migrated. Then you can design a migration solution or design a migration plan to migrate the server.
