How Do I Migrate a Server with a System Disk Larger Than 1 TB?
Background
SMS is restricted by an IMS limitation on the system disk size. When you use an image to create an ECS, the system disk cannot be larger than 1 TB. If the system disk of the source server to be migrated is larger than 1 TB, the migration can only be performed when certain conditions are met and the disk is resized.
Linux File-Level Migration
If the source system disk is larger than 1 TB but the disk usage is low, less than I TB of space used, you can resize the system disk and system partition of the target server before migration.
- Install the Agent on the source server. For more information, see Installing the Agent.
- Start the Agent. After the Agent is started, configure a target server by referring to Configuring a Target Server. When you configure the basic settings, select Yes for Partition Resize to resize the disks and partitions of the target server.
- In the Resize Partition window, set a new size for the system disk and partition as needed.
- Click Next: Configure Target to complete the migration configuration and start the migration.
