VMAX10K to VMAX250F Migration Prereq

Hi Experts,

We are in the process of migrating VMAX10k to VMAX250F via SRDF, what is the minimum enguinity version of VMAX10K to be interoperable with VMAX250F with HYPERMAX OS 5977.1131.1131.7366?

My other concern is that VMAX250F migration is designed to be migrated via NDM, so the license included on the BOM is NDM. But management decided to do it via SRDF. Do I need a separate SRDF license for the VMAX250F? Is this temporary? If yes, how long? Same concern for the VMAX10K, can I request also for a temporary license for this array?

Thanks,

Peter
