Starting data copy for a transition project

Contributors netapp-ivanad Download PDF of this page

You can initiate a data copy from 7-Mode volumes to ONTAP volumes for a baseline transfer. The baseline transfer starts when the data copy schedules configured in a project becomes active. After the baseline transfer is complete, the ONTAP volumes are updated periodically based on the data copy schedule.

  • You must have run a precheck on the project and resolved all errors.

  • You must have configured a dedicated, high-bandwidth, low-latency network between the source and destination systems for data transfer.

    Note You can use SnapMirror multipathing to balance the data transfer load between the two paths.
  • A data copy schedule must be configured for the session.

If you are transitioning to an existing SVM, the volumes are created during this operation. If you are transitioning to a new SVM, the SVM and its volumes get created during this operation.

SnapMirror relationships are created between 7-Mode and ONTAP volumes.

Steps
  1. Start the data copy:

    transition start -p project_name

    If the start operation fails and data copy is not started, you must resolve the issues and run the transition start command again.

    The project moves to the copy-baseline state. After the baseline transfer is completed, the project moves to the copy-update state.
