Understanding how a migrated file affects file state is essential. NFS-based tools such as rsync provide POSIX permissions. SMB-based tools such as emcopy create ACL permissions.
If SMB files from another vendor’s storage system are migrated to a PowerScale cluster, the shares, file data, security metadata, security identifiers, ACLs, ACEs, and inheritance attributes must all be migrated.
Datadobi greatly simplifies migrations by migrating all file permissions over to a PowerScale cluster.
