Snap Server Administrator Guide
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.
