Migrating an ECS to a DeH

Scenarios

ECSs can be migrated:

  • Between Dedicated Hosts (DeHs)
  • From a DeH to a public resource pool
  • From a public resource pool to a DeH

This section describes how to migrate an ECS from a public resource pool to a DeH.

  • Before migrating an ECS, ensure that there are available DeH resources.

  • For details about migrating ECSs from a DeH to another DeH or to a public resource pool, see "Migrating ECSs" in the Dedicated Host User Guide.

Constraints

  • Only stopped ECSs can be migrated.
  • To ensure that the migration is successful, there must be an available DeH.
  • CBR and CSBS backups are not affected by migrations.
  • ECS IDs remain unchanged after a migration.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and project.
  3. Under Computing, click Elastic Cloud Server.
  4. In the ECS list, locate the ECS to be migrated, choose More > View O&M and Monitoring > Reallocate ECS in the Operation column.
  5. In the displayed dialog box, select the target DeH.

    If no DeHs are available, create a DeH first. For details, see Allocating DeHs in the Dedicated Host User Guide.

  6. Click OK.
