Backing up the NIM database
You can back up the NIM database using SMIT, or the command line.
To back up the NIM database, you will be prompted for the name of a device or a file to which the NIM database and the /etc/niminfo file will be backed up. The level of the installed NIM master fileset will also be written to a file called /etc/NIM.level and saved in the backup. A backup of a NIM database should only be restored to a system with a NIM master fileset which is at the same level or a higher level than the level from which the backup was created.
