Getting Target Recommendations

Prerequisites

You have discovered resources, and grouped the resources as applications.

Procedure

1. Log in to the MgC console.
2. In the navigation pane on the left, choose Design > Migration Solutions. Select a migration project in the upper left corner of the page.

   On the Migration Solutions page, you can view the numbers of resources that can be migrated and that have got target configurations as well as the list of applications in the current project.

3. Click Assess in the Target Configuration card.
4. In the Select Application drop-down list, select the application you want to assess.
5. In the Select Resources area, select the application resources to be assessed.
6. Configure the assessment policy based on Table 1.

   Table 1 Settings used for computing target recommendations

   Parameter	Description
   Target Region	Select the region where you want to purchase resources on Huawei Cloud. You are advised to select a region close to your target users for lower network latency and quick access.
   Assessment Policy	Match source configuration MgC recommends the most appropriate Huawei Cloud resources based on source resource specifications. Match business scenario MgC recommends appropriate Huawei Cloud resources based on the business scenario of source resources and Huawei Cloud best practices. Cross-AZ migration This policy only applies to migration of ECSs between AZs on Huawei Cloud, and MgC only assesses servers in the application. You need to select the target AZ you want to migrate to. For details about how the system recommends appropriate target resources for you, see How Does MgC Recommend Appropriate Target Resources for Me?
   Priority	High performance MgC recommends target resources with optimal performance. Low cost MgC recommends target resources that are cheapest within the same family as source resources or the families you preferred.
   Preferences	Configure preferences for target servers. The servers that match your preferences are recommended first. For details about how the system recommends appropriate target resources for you, see How Does MgC Recommend Appropriate Target Resources for Me? ECS Types Select the expected ECS types. System Disk Select the system disk type you prefer. Data Disk Select the data disk type you prefer. Sizing Criteria Select the criteria that the system will follow for generating server recommendations. If you select Configuration-based, the system recommends target servers with the same or as close CPU and memory configurations as possible to the source servers. If you select Performance-based, you need to perform a performance collection for the source servers, and then set assessment parameters. The system will then recommend target servers with your desired CPU and memory specifications. NOTICE: The more performance data is collected, the more accurate the assessment is. The collection of server performance data should take no less than seven days.
   	For the container assessment, configure parameters such as Cluster Type, Cluster Version, and Container Network Model for getting recommendations on container resources.

7. Click Create Assessment. After the assessment task is complete, you can view the assessment results which include the recommended specifications of target resources. You can also view server performance data.
8. (Optional) Perform the following operations:
   • Modify recommended target configurations: You can modify recommended specifications of target servers and their disks.
   • Associate source servers with target servers: If you already have servers that match your requirements on Huawei Cloud, you can associate them with source servers.

Viewing the Assessment Results

In the application list on the Migration Solutions page, click View Target Configuration in the Operation column.

In the Target Configurations area, you can view the specifications of Huawei Cloud resources recommended based on the source resource specifications and your selected preferences. It also gives you the ability to estimate what it will cost to run your services on Huawei Cloud.

Viewing Server Performance Data

On the Target Configurations page, in the server list, you can view the average CPU and memory usage of each server in the last 7 or 30 days. Click Analyze Performance to view the performance statistics of all servers.

Modifying Recommended Target Configurations

1. In the Target Configurations area, locate the server that you want to modify the recommended target configurations for and click Modify Target Configuration in the Operation column.
2. Modify the specifications and image for the target server.

   

3. In the disk area, locate a disk and click Modify in the Target Specifications column. You can modify the disk type and capacity. Only Linux disk sizes can be decreased. If you downsize a disk, the system will set Disk Downsized to Yes. The reverse also applies.
   

   • The system disk capacity ranges from 40 GB to 1,024 GB.
   • The data disk capacity ranges from 10 GB to 32,768 GB.
   • Only Linux disk sizes can be decreased, and decreased sizes must be larger than the used sizes of source disks.
   • In the cross-AZ migration scenario, disk sizes can only be increased. Even if you decrease disk sizes here, the settings will not be applied, and the system will create target disks as large as source disks.
