Migration - Security issues with NDMP AND SnapMirror

[arghya]

Is there any issue or scenario that would keep permissions from being copied correctly during NDMP copy or during a snapmirror copy that is used in a migration project.

We had an outage where 20 people were affected by not having permissions to their data.  A snapmirror copy was used to migrate them to new storage.  The customer wants to know if permissions would not copy over for any reason.  We are using a combination of snapmirror and NDMP to migrate data.

Thanks.

One thing coming to my mind is, if there are permissions depending on "Local Groups" on the Storage Controller. They could be missing on the new Controller... THE major advantage when using Vfiler for CIFS data.
