我需要解决方案
1) If I'm is trying to move away from a Brocade Encryption Switch (BES) since it has been announced EOL, can NBU be used to unencrypt the tapes that were already encrypted with BES and then can NBU encrypt them again using different keys so that all these tapes' encryption keys can be migrated from BES to NBU (so BES can be removed completely eventually)?
2) If encryption is occurring at the tape drive by NBU KMS encryption, will there be backwards compatibility from LTO-7 to LTO-5 or LTO-4?
3) Would the unencryption of the tapes have to be done by the BES or NetApp DataFort (which the customer also has)?
