Before you decommission a media server, Symantec recommends that you do the following:

• Preview the actions of the nbdecommission command.

  Analyze the output of the preview operation to ensure that the command captures all references to the old server. If it did not, make a list of the items that the command does not cover and fix them manually later.

• Back up the NetBackup catalog before you begin. You can use it to return your environment to the pre-decommission state if something goes wrong or you have to abort the decommission.

• Run the command during a maintenance window when the load on the NetBackup environment is minimal.
