Guidelines and best practices for upgrading NetBackup appliances
This topic describes the guidelines and best practices that you should follow anytime you plan to upgrade appliance software.
Use the following information to help prepare for an appliance upgrade and to help avoid situations that can prevent a successful upgrade.
Always perform a full disaster recovery (DR) backup before an upgrade.
To make sure that there is enough space for the upgrade, delete all previously downloaded release updates, client packages, and client add-ons from the appliance before the upgrade. As a best practice, always remove downloaded packages after all appliances and clients have been upgraded.
If the appliance that you want to upgrade has ever had appliance version 2.6.0.1 installed, it requires a different method for client package removal.
Follow the same upgrade order for appliances as for traditional NetBackup upgrades. Always begin by updating the master server appliance, then upgrade all media server appliances.
If you have multiple media servers to upgrade, you must perform the upgrade process on each individual media server.
If a traditional NetBackup master server is used with a media server appliance, that master server must have the same NetBackup version or later as the media server appliance. For example, before you upgrade a media server appliance with NetBackup Appliance version 3.1.2, first upgrade the NetBackup software on the master server to version 8.1.2.
Make sure that the NetBackup master server is active and running throughout the duration of an appliance media server upgrade. In addition, make sure that the NetBackup processes are started or running on both the master server and the media server.
Note:
Only NetBackup services should be active during an upgrade. All jobs must be stopped, suspended, or prevented from running during an upgrade.
NetBackup clients must use the same or an earlier software version as the appliance. Clients cannot run at a later version than the appliance. For example, a client with NetBackup version 8.1.2 can only be used with an appliance server with version 3.1.2 or later. Client add-ons must also be the same as the client version.
