This topic provides information about upgrading the TrueSight IT Data Analytics product from an earlier version.
The upgrade process requires you to upgrade all the components of the product to the latest version. For example, you cannot use Collection Station of an earlier version with all other components upgraded to the latest version. This is important to avoid potential problems and errors.
This topic contains the following information:
Ensure that the following requirements are met:
Depending on your operating system, ensure that the following environment variable is already set.
Create a back up of all the indexed data at an appropriate location. For more information, see Backing up and restoring data.
If you are operating in a multiple-server deployment, the order in which you upgrade the components and the order in which you start the components is important.
Unless upgrade of all the components is completed, do not start any of the component services.
You need to upgrade the components in the following order of priority. The following order also applies for starting the services post-upgrade. For more information, see Starting or stopping product services.
Start the installation program by running the setup (for Windows) or setup.bin (for Linux) file. Click Next.
The type of installation you performed (earlier), determines the type of upgrade. Depending on the type of upgrade, perform the steps described in the following table:
|Typical install||Depending on your platform, you can choose to keep the following check box selections unchanged and click Next:|
The Installation Preview screen is displayed, providing information about the features to be installed, the total disk size, the destination directory, and so on.
Click Install to start the upgrade.
(Optional) Click View Log to see the installation log.
To exit the installation program, click Done.
By default, the following environment variable pointing to the product installation path is automatically set:
To view the upgraded version of the product, reload the current browser page so that the cached content is ignored.

(Optional) If you want to enable security for the Console Server, you need to configure the system. For more information, see Enabling security for the Console Server and Search components.
After you upgrade, search on field values works in a case-insensitive way on new data collected. Conversely, search on field values that form part of existing data (or old data) continues to work in a case-sensitive way.
Case-insensitivity for field and tag values can impact existing saved searches and associated dashboards and notifications. As a result of case-insensitivity, it is possible that you see more results on running the saved search as compared to the previous version of the product. Also, case-insensitivity can impact the product performance if you are operating in a large scale environment. For more information, contact BMC Support. Additionally, you can see the following topics that provide scaling recommendations for version 2.7.00 of the product:
You can turn case-insensitive searches into case-sensitive searches by adding the CASE function in the search string. For more information, see Search string syntax.
After upgrading, if you create an Upload file type of data collector to collect past data, then it is possible that the data collected is added to an existing index. As a result, search performed on this data will work in a case-sensitive way.
If you have existing external configurations for TrueSight Infrastructure Management (or ProactiveNet) cells, then you might need to edit them and change the encryption key. Changing the encryption key is required if TLS is enabled for TrueSight Infrastructure Management on TrueSight Operations Management 10.7. In this scenario, you also need to import the certificates generated on the TrueSight Operations Management side to be able to create new external configurations in version 2.7 of IT Data Analytics. For more information, see Enabling security for communication with Infrastructure Management server.
While running the upgrade, it is possible that you see the Feature Configuration Database failed error on the Installation Summary screen. This error is likely to occur in a scenario if you upgraded from version 2.0.00 to 2.1.00 and then to 2.7.00. This issue can occur due to a conflict between a user and its role mapping that might have occurred in version 2.1.00 of the product. To resolve the issue, please contact BMC Support.
If you face any other upgrade-related issues, consider rolling back to an earlier version before you try upgrading again. For more information, Rolling back a failed upgrade.
(Optional) Start using Atrium Single Sign-On 9.0 as your authentication mechanism by running the enablesso CLI command CLI command. Using Atrium Single Sign-On is important if you plan to use IT Data Analytics in conjunction with the TrueSight products. For more information, see User authentication options.
