Step 3: Assess Migration Readiness

Measure whether the source servers are ready to migrate from the items of basic configuration, network environment, and migration group.

Prerequisites

Procedure

  1. On the Application Discovery page, click the Resources tab and click Server in the Category column or the number in the Server row.

  2. On the top of the server list, choose Migration Scenario > Server migration.

  3. Locate a source server and move the cursor to Not ready in the Migration Readiness column. You can view the configurations that need to be completed to make the server ready. You need to associate the server with an Edge device and a credential, and add the server to an application, pass the migration pre-check (automatically triggered), and add the server to an application. Click Configure in the Edge Device or Credential column.

  4. Configure the parameters listed in Table 1.

    Table 1 Parameters for configuring migration readiness

    Parameter

    Configuration

    Type

    Set this parameter based on the source server OS type.

    Edge Device

    Select the Edge device prepared in Step 1: Download and Install Edge. If there are a large number of servers to be associated with this Edge device, you can select these servers and click Manage Device Association above the list to associate them in a batch.

    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. During the migration, Edge accesses the source server through this IP address.

    Port

    Select the source server's port that allows traffic from Edge.

    • By default, port 5985 on Windows source servers must be opened to the Edge device. The port cannot be changed.
    • By default, port 22 on Linux source servers must be opened to the Edge device. You can specify a different port if needed.

    Credential

    Select the server credential you added to Edge. If the credential has not been added to MgC, go to the Edge console and add the server credential to the Edge device and synchronize it to MgC.

  5. Click Confirm. The system performs checks whether the source server can be accessed from the Edge device using the information you provided, and collect resource details again if necessary. The pre-check takes about 10 seconds.
  6. Add the source server to an application. For details, see Grouping Resources as Applications. Check whether Ready is displayed in the Migration Readiness column.

    To reduce migration risks, you are advised to group no more than 30 servers as an application. If more than 30 servers need to be migrated, group them as multiple applications.

    If you want to refine an application, go to the Application Discovery page, click the application you want to refine, and add or remove servers from the application.
