NAME

DESCRIPTION

When you create a migration, provide the required information to let Application Migration access the source environment. Application Migration uses this information to access the application in the source environment and discover application artifacts.

All Oracle Cloud Infrastructure resources, including migrations, get an Oracle-assigned, unique ID called an Oracle Cloud Identifier (OCID). When you create a resource, you can find its OCID in the response. You can also retrieve a resource’s OCID by using a List API operation on that resource type, or by viewing the resource in the Console. For more information, see Resource Identifiers.

After you send your request, a migration is created in the compartment that contains the source. The new migration’s lifecycle state will temporarily be <code>CREATING</code> and the state of the migration will be <code>DISCOVERING_APPLICATION</code>. During this phase, Application Migration sets the template for the <code>serviceConfig</code> and <code>applicationConfig</code> fields of the migration. When this operation is complete, the state of the migration changes to <code>MISSING_CONFIG_VALUES</code>. Next, you’ll need to update the migration to provide configuration values. Before updating the migration, ensure that its state has changed to <code>MISSING_CONFIG_VALUES</code>.

To track the progress of this operation, you can monitor the status of the Create Migration and Discover Application work requests by using the <code>`GetWorkRequest <https://docs.cloud.oracle.com/en-us/iaas/tools/oci-cli/latest/oci_cli_docs/cmdref/application-migration/work-request/get.html>`__</code> REST API operation on the work request or by viewing the status of the work request in the console.

USAGE

oci application-migration migration create [OPTIONS]

REQUIRED PARAMETERS

Name of the application that you want to migrate from the source environment.

The OCID <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm> of the compartment that contains the source.

This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

The OCID <https://docs.cloud.oracle.com/iaas/Content/General/Concepts/identifiers.htm> of the source.

OPTIONAL PARAMETERS

Configuration required to migrate the application. In addition to the key and value, additional fields are provided to describe type type and purpose of each field. Only the value for each key is required when passing configuration to the CreateMigration operation.

This option is a JSON dictionary of type dict(str, ConfigurationField). For documentation on ConfigurationField please see our API reference: https://docs.cloud.oracle.com/api/#/en/applicationmigration/20191031/datatypes/ConfigurationField. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags <https://docs.cloud.oracle.com/Content/General/Concepts/resourcetags.htm>. Example: {“Operations”: {“CostCenter”: “42”}} This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

Description of the application that you are migrating.

User-friendly name of the application. This will be the name of the migrated application in Oracle Cloud Infrastructure.

Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags <https://docs.cloud.oracle.com/Content/General/Concepts/resourcetags.htm>. Example: {“Department”: “Finance”} This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link: https://docs.cloud.oracle.com/iaas/Content/API/SDKDocs/cliusing.htm#AdvancedJSONOptions

If set to true, Application Migration migrates the application resources selectively depending on the source.

The maximum time to wait for the work request to reach the state defined by --wait-for-state. Defaults to 1200 seconds.

The pre-existing database type to be used in this migration. Currently, Application migration only supports Oracle Cloud Infrastructure databases and this option is currently available only for JAVA_CLOUD_SERVICE and WEBLOGIC_CLOUD_SERVICE target instance types.

Accepted values are:

DATABASE_SYSTEM, NOT_SET

Configuration required to migrate the application. In addition to the key and value, additional fields are provided to describe type type and purpose of each field. Only the value for each key is required when passing configuration to the CreateMigration operation.

This option is a JSON dictionary of type dict(str, ConfigurationField). For documentation on ConfigurationField please see our API reference: https://docs.cloud.oracle.com/api/#/en/applicationmigration/20191031/datatypes/ConfigurationField. This is a complex type whose value must be valid JSON. The value can be provided as a string on the command line or passed in as a file using the file://path/to/file syntax.

The --generate-param-json-input option can be used to generate an example of the JSON which must be provided. We recommend storing this example in a file, modifying it as needed and then passing it back in via the file:// syntax.

This operation asynchronously creates, modifies or deletes a resource and uses a work request to track the progress of the operation. Specify this option to perform the action and then wait until the work request reaches a certain state. Multiple states can be specified, returning on the first state. For example, --wait-for-state SUCCEEDED --wait-for-state FAILED would return on whichever lifecycle state is reached first. If timeout is reached, a return code of 2 is returned. For any other error, a return code of 1 is returned.

Accepted values are:

ACCEPTED, CANCELED, CANCELING, FAILED, IN_PROGRESS, SUCCEEDED

Check every --wait-interval-seconds to see whether the work request to see if it has reached the state defined by --wait-for-state. Defaults to 30 seconds.
