Enable Concurrency

You can set the maximum number of processes that the SMS-Agent can start concurrently (1 to 4) when migrating and synchronizing files of a Linux source server. However, the number of process that can actually be started depends on how well the source server performs and how many disks and partitions the source server has.

Advanced Options

• Advanced options Exclude Migration Paths, Include Sync Paths, and Exclude Sync Paths are available for Linux file-level migrations. 
• Advanced options Data Compression and Compression Threads are available for Linux file-level migrations. 
• For a Windows block-level migration over a private network, Transit IP Address is available.

Set Migration Limits

You can set limits for CPU usage, memory usage, and disk throughput for SMS-Agent on the source server.

How Do I Set Resource Limits for SMS-Agent During a Linux Server Migration?

1

Check Network Performance

During the first full migration, a subtask will be generated to check the migration network performance by detecting the packet loss rate, jitter, network latency, bandwidth, memory usage, and CPU usage.

Start Target Upon Launch

When configuring the destination ECS, select the status of the destination ECS after the migration is complete.

Deleting an EVS Snapshot

SMS generates snapshots for EVS disks on each target server during the full replication, incremental synchronization, and target cloning. For EVS disks in DSS storage pools, snapshots take up the same amount of space in the pool as the disks.

Migrating servers to enterprise projects

SMS allows you to migrate a server to a specific enterprise project.

New SMS console

• Migration Template: A migration template defines the migration network type, migration rate limit, whether to enable continuous synchronization, and region and project. You can use a template to quickly configure migration tasks.
• Server Template: A server template defines the target server VPC, subnet, and security group. You can use a template to quickly configure target servers with the same settings.

Continuous synchronization

• If you choose not to execute a continuous synchronization after the full replication, SMS will not perform a continuous synchronization and will automatically launch the target server. To synchronize incremental data, click Start in the Operation column.
• If you choose to execute a continuous synchronization after the full replication, SMS will perform a continuous synchronization. To complete the migration, you need to manually launch or clone the target server.

Locking target servers

After the migration starts, SMS automatically locks the target server. During this period, you are not allowed to operate the target server. This prevents migration failures.

New SMS console

• Continuous Synchronization: After the full replication is complete, SMS automatically performs continuous synchronization, freeing you from manually synchronizing data.
• Clone Target Server: Before you launch the target server, you can clone the target server for service testing, and only launch the target server until tests confirm there are no issues.
• Project Management: You can manage your source servers by migration project.

Migration to yearly/monthly ECSs

The source servers can be migrated to pay-per-use or yearly/monthly ECSs. You can select ECSs of whichever billing mode is appropriate.
