Server Migration Center:VMware migration without agents

Last Updated:Jul 06, 2023

Server Migration Center (SMC) allows you to migrate VMware VMs to Alibaba Cloud without the need to install agents or modify the operating system settings of Server Migration Connector. This improves the efficiency of business migration to Alibaba Cloud and eliminates your concerns about business security and business performance during the migration. This topic describes the benefits, scenarios, and limits of VMware migration without agents.

Benefits

  • No resource consumption

    The SMC client does not run inside VMs. Therefore, the migration does not consume the resources of VMs.

  • High migration efficiency

    You do not need to separately install an agent for each VM. This reduces the costs of labor and time.

  • High security

    No operations are performed within the operating system of a VM. This eliminates your concerns about security.

  • High compatibility

    The migration does not depend on the internal environment of the VM operating system. This improves the success rate of the migration.

Scenarios

  • Scenario 1: Integrate cloud resources

    You want to better integrate resources and improve efficiency, and maximize the use of cloud resources.

  • Scenario 2: Reduce costs

    You want to reduce the costs of infrastructure and hardware, such as servers and storage devices.

  • Scenario 3: Improve security

    You want to use the strong security technologies and powerful security capabilities of Alibaba Cloud to improve the security level of your enterprises.

  • Scenario 4: Improve flexibility

    You want to use the auto scaling feature to adjust storage capacity based on your business requirements. This way, your enterprise can be more flexible and adaptable.

Features

  • VMware migration without agents

    SMC allows you to migrate VMware VMs to Alibaba Cloud without the need to install agents or modify the operating system settings of Server Migration Connector. This improves the efficiency of business migration to Alibaba Cloud and eliminates your concerns about business security and business performance during the migration.

  • Incremental data migration from a VMware VM without an agent

    SMC allows you to migrate incremental data from a VMware VM to Alibaba Cloud. You can specify the time interval between incremental migration jobs. Incremental data migration reduces the VM downtime and the total duration of the migration.

Migration process

References

ECS

During VMware migration without agents, you can first use the snapshots of VMware VMs to convert the VMs into ECS images. Then, you can generate ECS instances based on the ECS images.

Snapshot

During VMware migration without agents, the system creates snapshots for VMware VMs in the intermediate stage.

Snapshot overview

Image

During VMware migration without agents, custom ECS images are generated based on snapshots to create ECS instances.

Tag

You can use tags to manage and categorize migration sources and migration tasks. This helps simplify subsequent queries and batch operations.

Use tags to manage migration sources and migration tasks

VPC

During VMware migration without agents, data is migrated over the Internet or in a VPC.

Resource Access Management (RAM)

RAM is a service that is used to manage user identities and resource access permissions. You can use RAM to control the operation permissions of users. This allows you to implement fine-grained permission management for SMC resources.
