Explanation:
The correct order of steps to migrate from an old array to a new one without disruption using VPLEX is:
* VPLEX discovers the new array and the admin creates migration target devices.
* VPLEX admin initiates mobility job(s).
* Once volumes on the new array are fully synchronized, the admin commits the migration.
* VPLEX admin monitors progress of the migration; I/O to host continues.
* Connect new storage array to VPLEX.
* Discovery and Creation: The initial step involves VPLEX identifying the presence of a new storage array within its environment. Following this discovery, a system administrator is responsible for setting up migration target devices on this newly recognized array.
* Initiation of Mobility Jobs: Subsequently, a system administrator must initiate mobility jobs through the VPLEX management interface, which facilitates data movement from the existing source storage to the target devices on the new array.
* Synchronization and Commitment: After initiating mobility jobs, data synchronization between source and target arrays begins automatically. Once synchronization reaches completion, indicating that both arrays have identical data sets, an administrator must commit to finalizing this stage of migration.
* Monitoring Migration Progress: Throughout this process, it's crucial for an administrator to monitor ongoing operations ensuring that input/output operations continue uninterrupted for hosts accessing data during transition phases.
* Connecting New Array: The final step involves integrating the newly populated storage array into production by connecting it with VPLEX systems thus completing migration.
