LCM Import

Initiates import of a Migration snapshot so that the contents of the application snapshot are imported into the application.

The presence of status -1 in the response indicates that the import is in progress. You should use the job status URI to determine whether the import is complete.

If the Job completes with status 1, the task details will be mentioned in the items from which the source, destination, and URL to fetch the first set of errors is available. All issues for a particular task can be fetched in the manner of pagination. Acceptable values for msgtype are: error/warn/info; limit represents the number of issues requested per request, and offset marks the beginning number to fetch the issues.

This API is version 11.1.2.3.600.

Before using the REST resources, you must understand how to access the REST resources and other important concepts. See About the REST APIs. Using these REST APIs requires prerequisites. See Prerequisites.
