   A manufacturing company is planning an NDM migration of 50 LUNs from a legacy VMAX to a new PowerMax. The storage team has confirmed that the source and target arrays are at compatible PowerMaxOS levels and that the hosts are zoned to both arrays. Before starting the migration, the team wants to ensure that the target LUNs are correctly sized and that the migration will not fail due to configuration mismatches. What should the team do first?

   • AReboot all hosts to ensure they recognize the new target LUNs before starting the migration.
   • BValidate that the target LUNs are the same size or larger than the source LUNs and that the masking views are correctly configured on the target.
   • CDelete the source LUNs from the source array to free up space for the migration.
   • DDisable the host multipathing software to prevent I/O conflicts during the migration.

   How does Non-Disruptive Migration (NDM) improve operational efficiency?

   • ABy reducing the number of storage administrators needed
   • BBy allowing migrations to occur during business hours without disrupting users
   • CBy automatically tuning the target array for optimal performance
   • DBy requiring less planning and preparation than traditional migrations

   A media streaming company is migrating its content repository from an older PowerMax to a new PowerMax 2000 to take advantage of higher performance. The migration must not interrupt the streaming service, and the storage team wants to minimize the risk of data loss during the cutover. What is the primary benefit of using NDM in this scenario?

   • AIt guarantees that the migration completes in under one hour regardless of the data volume.
   • BIt reduces risk by keeping the source and target synchronized until the cutover, allowing a rollback if needed.
   • CIt eliminates the need for any host configuration changes before, during, or after the migration.
   • DIt automatically deletes the source LUNs after the cutover to free up capacity.

   What is an important operational consideration before starting a Non-Disruptive Migration (NDM)?

   • AEnsuring the source and target arrays are the same model
   • BDisabling all host access to the source array
   • CVerifying that the target array has sufficient capacity and connectivity
   • DEnsuring the source array is running the latest firmware
