   A hospital is migrating a critical patient-records volume from an older VMAX array to a new PowerMax 2500. The migration must not interrupt the electronic health record (EHR) application, which has an aggressive I/O profile and strict latency requirements. The storage team has verified that the source and target arrays are in the same Unisphere environment and that the target has sufficient capacity. What is the most important additional consideration before initiating the non-disruptive migration?

   • ASchedule the migration during a maintenance window, as non-disruptive migrations still require a brief application outage during cutover.
   • BConfirm that the source volume is not part of any consistency group, as non-disruptive migration only supports individual volumes.
   • CVerify that the source array is running PowerMaxOS 10 or later, as older arrays cannot be migration sources.
   • DEnsure the target SRP has enough performance headroom to handle the combined workload during the copy phase.

   A financial services firm is planning to migrate a 10 TB production database volume to a new PowerMax. The source volume is heavily used and the migration must not impact performance. The storage administrator has checked that the target array has enough raw capacity. What additional prerequisite check is essential to ensure the migration does not degrade application performance?

   • AConfirm that the target SRP has sufficient available performance capacity (IOPS and bandwidth) to handle the migration copy plus normal production I/O.
   • BCheck that the source and target arrays are in the same data center, as non-disruptive migration does not support remote arrays.
   • CEnsure that the source volume is thin-provisioned, as fully provisioned volumes cannot be migrated non-disruptively.
   • DVerify that the source and target arrays are connected via a supported distance and have adequate replication bandwidth.

   A company is migrating a critical application volume from an old VMAX to a new PowerMax. The application has a strict SLA that requires zero downtime. The storage team has verified that the source and target arrays are compatible and have sufficient capacity. However, the application team is concerned about the migration's impact on performance. What is the best way to address this concern?

   • APerform the migration on a test volume first to measure the performance impact before migrating the production volume.
   • BSchedule the migration during off-peak hours to minimize the impact on application performance.
   • CExplain that non-disruptive migration is designed to minimize performance impact by throttling the copy process to prioritize production I/O.
   • DReassure the application team that the migration will have zero performance impact, as it runs entirely in the background.
