The OES 11 migration tool, which run on the target OES 11 server, must mount the remote file systems of the source servers in order to obtain information about the source volumes and to copy the specified data to the target server.
For NetWare and OES 1 Linux migrations, the mls and migfiles commands require an NCP mount. They use the ncpmount command to map the remote volume to /var/opt/novell/migration/<Project Name>/fs/mnt/source, and then read data from the _admin volume to validate the source path. These commands unmount the file system upon termination. If the process is killed forcibly (kill -9), the mount point remains mounted and must be unmounted by the administrator.
For source OES 2 Linux and OES 11 servers, the mls command uses nbackup tool to build the list of trustees.
