Migrating a Domain

You can use the ldm migrate-domain command to initiate a migration of a domain from one system to another system.

For information about the migration options and operands, see the ldm(1M) man page.

Performing a Dry Run

When you provide the -n option to the migrate-domain subcommand, migration checks are performed, but the source domain is not migrated. Any requirement that is not satisfied is reported as an error. This allows you to correct any configuration errors before attempting a real migration.

Performing Non-Interactive Migrations

Until the release of the Logical Domains 1.3 software, migrations were interactive operations. When you initiated the migration, you were prompted for the password to use for the target machine. Starting with Logical Domains 1.3, you can use the ldm migrate-domain -p filename command to initiate a non-interactive migration operation.

The file name you specify as an argument to the -p option must have the following properties:

• The first line of the file must contain the password

• The password must be plain text

• The password must not exceed 256 characters in length

A newline character on the end of the password and all lines that follow the first line are ignored.

The file in which you store the target machine's password must be properly secured. If you plan to store passwords in this manner, ensure that the file permissions are set so that only the root owner, or a privileged user, can read or write the file (400 or 600).
