Expansion Arrays However, when migrating from a Windows source to a Unix SnapTree, permissions cannot be retained (since Unix snaptrees are required to be Unix personality throughout). Files and directories will inherit the Unix personality and will have a set of default Unix permissions. Migrating from a GuardianOS Server When migrating from one GuardianOS server to another, it is recommended that you maintain the same security model on the target server that you have on the source. • If your source server uses a Windows SnapTree and has permissions assigned to Windows domain users, use a Windows connection for migration. Windows permissions will be retained exactly as they are on the source, with the same enforcement limitations for unknown users as for migration from Windows servers (see Migrating from a Windows Security Model to a Windows SnapTree). Note If migrating from a pre-5.0 GuardianOS server, Windows permissions will be retained verbatim, but may have different meaning due to the differences between the pre-5.0 POSIX ACL security model and the Windows security model introduced in 5.0. • If your source server uses a UNIX SnapTree and has permissions assigned to local or NIS users, use an NFS connection for migration. Note Local users that have UNIX permissions on the source will not be created on the target with the same UIDs. Migrating from a SnapOS Server When migrating from a SnapOS Server to a GuardianOS server, permissions will not be correctly retained. Expansion Arrays Note This section does not apply to the Snap Server 110 or 210. To increase the capacity of a Snap Server, Adaptec offers the SANbloc S50 expansion array.
