Upgrading Data Insight to 4.5.1


Upgrading Data Insight to 4.5.1
Prev	Upgrading Symantec Data Insight	Next

You can upgrade an existing Data Insight Server with Symantec Data Insight versions 3.0.1, 4.5, and 4.0 to 4.5.1. Data Insight does not support upgrading a version before 4.5 directly to 4.5.1. If the server is installed with a version before 4.5, you must upgrade to version 4.5 before you can upgrade to 4.5.1.

All Data Insight worker nodes must be at the same level of major version as the Management Server. Windows file server agents can be one level lower than the Management Server version. Thus, Management Server 4.5.1 is compatible with 3.0RU1 (3.0.1), 4.5, and 4.0 version of Windows File Server agents. This gives you enough time to plan the upgrade of your Windows File Server agents.

Before you begin the upgrade to Symantec Data Insight 4.5.1, note the following:

As a best-practice measure, Symantec recommends that you take a backup of the server's data folder.
In case of a multi-node setup, the upgrade setup must be run first on the Management Server, then on the Indexer nodes, followed by the Collector nodes. You can upgrade the Windows File Server agent only after upgrading the Collector nodes.
If you have archived older index segments, ensure that you restore the archived segments before upgrading the server.
If you are upgrading the server using a Remote Desktop Connection (RDC), ensure that you do not set automatic log-off for the session.
The upgrade from 3.0.1 is likely to take a longer time since new cache files are generated on each index folder for a share for the first time

See Names and locations of cache files.
The size of the data directory on the Indexer nodes increases by about 5% after the upgrade from 3.0.1. The increase in size depends on the time period configured for capturing activity data. The increase in the size of the data directory may also vary depending on the number of audit events that are captured on configured shares.

Ensure that you complete the following tasks after the upgrade:

Configure the primary attributes that are used to classify users for the purpose of generating advanced analytics data.
Configure the time period for computing advanced analytics.
Refresh the Data Insight Dashboard data.

For information about configuring settings for advanced analytics, see the Symantec Data Insight Administrator's Guide.

To upgrade Data Insight to 4.5.1:

Log in as Administrator to the server that you want to upgrade.
In case of a Linux indexer, log in as the appropriate user (root or non-root) configured to run the product.

Note that if you had earlier installed the Linux Indexer as root and later switched to using a non-root user, you must perform the following steps before you start the Linux installer for upgrade. If you do not perform these steps, the installer you launch with non-root credentials cannot detect the previous version of Data Insight on the server.
- Log in to the machine as root user.
- Copy the following file to a temporary location:
  
  ~/.java/.userPrefs/com/install4j/installations/prefs.xml.
- Log out and log back in as the non-root user.
- Create the following directory:
  
  ~/.java/.userPrefs/com/install4j/installations/
- Change to the directory you have created.
- Take a backup of prefs.xml.
- Overwrite prefs.xml in this folder with the one you copied to the prefs.xml that was copied to the temporary location.
To launch the Symantec Data Insight 4.5.1 installer, double-click Symantec_DataInsight_linux_45RP1_4_5_1_5221_RHEL6_x64.exe, where,
- N is the build number, and
- PP is the architecture - x86:32 bit, x64:64 bit.
  
  On Linux, launch the corresponding Symantec_DataInsight_linux_45RP1_4_5_1_5221_RHEL6_x64.sh script.
When the setup prompts you to upgrade from current version to 4.5.1, click Yes.

Note:

On Linux, if the installer does not prompt you for upgrade because it does not detect the earlier version of Data Insight on the machine, ensure that you first follow the instructions in 1.
In the Welcome to the Symantec Data Insight Setup Wizard window, click Next.
In the License Agreement window, select I accept the agreement, and click Next.
You must upgrade the product data before you start Data Insight services. In the Completing the Symantec Data Insight 4.5.1 Upgrade Wizard window, select the Launch the Upgrade Data Wizard check box.
Click Finish to exit the setup.

See Upgrading the product data using the Upgrade Data Wizard.

Note:

You can also upgrade the Windows File Server agent and Collector nodes using the Management Console. For more details, see the Symantec Data Insight Administration Guide.
