DLm6000 with VNX7500 data migration into DLM8100 with Data Domain

Hi Team,

We are having DLm6000 with VNX7500 as Disk Lib for Mainframe. We are planning to migrate DLm6000 to DLm8100 with Data Domain as back-end storage. Since DLm6000 + VNX uses Legacy file system and DLm8100+Data Domain Enhance file system model, what would be the data migration strategy. Do we have hardware based migration in place or have to use tape to tape copy using ISVs. Please let me know if anyone gone into this. Thanks.

Kind regards,

Anthony
