Upgrade considerations

Before you upgrade your NetVault Backup system, review the following notes.

•
When you perform an upgrade, select the server or client version based on the current installation type.
•
Upgrade the NetVault Backup Server before upgrading any client system.
•
A NetVault Backup Server can only support clients of the same version as itself or older. The NetVault Backup Client software version cannot be higher than the NetVault Backup Server software version.
•
Starting with 10.0, the NetVault Backup Server installation is only supported on Windows and Linux operating systems. You can no longer install the NetVault Backup server on UNIX and Mac OS X operating systems.
For information about supported operating system versions, see the Quest NetVault Backup Compatibility Guide available at https://support.quest.com/technical-documents.
•
Upgrade to NetVault Backup 12.3 and later is only supported from NetVault Backup 10.0 and later.
•
When you upgrade NetVault Backup on Linux-based systems, it removes all start and stop links to the netvault init script before resetting them to the runlevels of the new version. If you want to retain any user-defined links to the init script after an upgrade, do not use the word “netvault” in the link name.
•
To simultaneously upgrade the NetVault Backup Client software on multiple machines, you can use the push installation method of NetVault Backup WebUI. You can use this method for both new and upgrade installations. For more information about this method, see the Quest NetVault Backup Administrator's Guide.
•
During upgrade, the language must be the same as the original language when NetVault Backup was first installed. If the language during upgrade differs from the original language, the default administrator account will not migrate successfully and the NetVault Backup instance may get locked.
•
Before upgrading NetVault Backup to version 11.4.5 or later, you must upgrade the attached DR appliance to version 4.0.3 or later.
•
If an external installation of RDA version 3.2 is present, either remove it or upgrade it to the RDA version 4.0.3041.0 or later.
•
All the DR devices that were attached to the previous version NetVault Backup, must be reachable and online during the upgrade process.
•
DR devices that are either not reachable or running on DR OS version less than 4.0.3 are grouped under Orphan Devices. Remove these devices first and then re-add to NetVault Backup after the upgrade.
•
To ensure the smooth operation of NetVault Backup, after upgrading NetVault Backup to version 12.3, you must clear the browser cache.
•
To upgrade NetVault Backup server to version 12.3 or later, login with the user account used for installing the previous version of the NetVault Backup, and run the setup. The PostgreSQL upgrade fails if you upgrade NetVault Backup using a different user account.
•
There is an expected latency of a few minutes to load NetVault Backup WebUI pages such as Dashboard, View Reports, and Create Backup Job, immediately after NetVault Backup installation or upgrade.

Preparing for an upgrade

•
Back up the NetVault Database: The first step in preparing for an upgrade of NetVault Backup Server is to perform a backup of the existing NetVault Database. If an upgrade is unsuccessful, you can reinstall the previous version of NetVault Backup and recover the NetVault Database to enable troubleshooting of the failed upgrade without interfering with an existing backup schedule.
 
For more information about backing up the NetVault Database with the Plug-in for Databases, see Quest NetVault Backup Built-in Plug-ins User’s Guide.
When you restore data from the NetVault Database, the logs are restored to the directory logs_restored_<YYYYMMDD>.
•
Close all other NetVault Backup applications: Before starting the upgrade procedure, close all other NetVault Backup applications, such as NetVault Configurator, Workstation Client, and PostgreSQL pgAdmin. If you have opened any configuration file, make sure that the file is closed before you start the upgrade procedure. On Windows, it may also be necessary to close Event Viewer before performing an upgrade. On Windows, close all the command prompts where any of the NetVault directories are browsed.
•
Disable anti-virus software: We recommend that you disable the anti-virus software before installing or upgrading NetVault Backup. The installation process may conflict with the anti-virus software and various NetVault Backup operations may fail to function properly after the installation if you do not disable the anti-virus software.
