Migrating a Storage System AD Domain (Applicable to V300R006C30 and Later)

Context

• After the AD domain on the user network is migrated, the storage system must exit from the original AD domain and be added to the new AD domain.
• If the storage system is configured with cross-protocol user mappings before AD domain migration, the mappings will become invalid after the storage system is added to the new AD domain. You need to configure the mappings again.
• If the storage system creates AD domain user quota before AD domain migration, the quota will become invalid after the storage system is added to the new AD domain. You need to create the quota again.
• After the storage system is added to the new AD domain, users of the new AD domain can perform operations in the CIFS shared directory and have the same operation permissions as those of the original AD domain.

Procedure

1. Log in to the CLI of the storage system and run the change domain ad_config sid_history_enable=yes command to enable the AD domain migration function.

   If the message Command executed successfully is displayed, the function is enabled successfully. If it is not, perform operations as prompted and enable the AD domain migration function again.
