The correct sequence follows the standard lifecycle of a storage migration project. The process begins with preparation, which involves setting up the migration environment (e.g., zoning, connectivity) and then creating the specific migration session where source storage is discovered and target storage is provisioned. The execution phase follows, where data is synchronized in the background, followed by a non-disruptive cutover that redirects host I/O to the new array. Once the cutover is complete and validated, the migration is finalized by committing the changes, which makes the move permanent. Finally, the cleanup phase involves removing the now-redundant migration infrastructure.

Dell PowerMax: Migration Technologies (White Paper): This document outlines the process for Non-Disruptive Migration (NDM). The workflow described follows the sequence of:

Setup: Creating a migration session in Unisphere.

Execution: Involves multiple states such as Synchronized, and then a user-initiated Cutover.

Commit: A final Commit operation is performed to complete the migration and sever the relationship with the source.

Cleanup: Deleting the migration session. This validates the logical flow from setup to cleanup. (Reference Section: NDM operations)

Unisphere for PowerMax Online Help Documentation: The built-in help for the Unisphere management software details the step-by-step wizard for performing an NDM. The wizard guides the user through environment setup, device selection (discovery and provisioning), initiating the synchronization/cutover, and finally committing or aborting the session. The final step outside the wizard is always to decommission the old paths and connectivity.
