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.

  1. Install the Agent on the source server. For more information, see "Installing the Agent".
  2. 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.

  3. In the Resize Partition window, set a new size for the system disk and partition as needed.
  4. Click Next: Configure Target to complete the migration configuration and start the migration.
