Discover Upgrade Manual
Preparing to Upgrade to the Current® Release
To upgrade your Unica Discover solution, review the entire process before you commence the upgrade. The process that you follow varies depending on the number of servers that are deployed in your Unica Discover solution.
Getting Started with the Upgrade
When you are ready to begin your upgrade, complete the following steps just before you begin your upgrade.
Stopping Traffic at the HBR
In an HBR environment, there is no need to stop traffic. As soon as a Processing Server is no longer available to receive hits, traffic is diverted to other available Processing Servers or spooled locally to the HBR disk until servers become available.

  - Overview of the Upgrade Process
    The objective of the upgrade is to minimize downtime and data loss. The recommended approach is to suspend the processing components, letting data spool to disk while the Data Collector collects any unaggregated statistical data. The system can then be upgraded. When it is restarted, it will attempt to work off the spooled data until it catches up.
  - Upgrading and Migrating to New Hardware
    If you are deploying new hardware in conjunction with your upgrade, please complete the upgrade in the following general steps.
  - Upgrades and the web.config file
    If you have customized your configuration by modifying the web.config file, running the Upgrader does not affect your customization.

      - Stopping Traffic at the HBR
        In an HBR environment, there is no need to stop traffic. As soon as a Processing Server is no longer available to receive hits, traffic is diverted to other available Processing Servers or spooled locally to the HBR disk until servers become available.
      - Stopping Traffic into Each Canister
        Before upgrading, traffic must be stopped into the processing pipeline of each Discover Canister.
      - Completing Data Collection
        After traffic stops and immediately before you begin upgrading your Unica Discover platform and core applications, you should verify that the latest execution of the Data Collector is complete.
      - Remove Canister Spool Files
        To remove the Canister spool files from your existing Unica Discover installation:

  - Testing Your Discover Solution
    After you complete installation and the initial configuration tasks for each licensed Discover product and module, verify the operations of your Discover solution. This section provides a simple procedure for testing end-to-end operations of the Discover solution, with modifications based on optional components that you may have installed.

Stopping Traffic at the HBR

In an HBR environment, there is no need to stop traffic. As soon as a Processing Server is no longer available to receive hits, traffic is diverted to other available Processing Servers or spooled locally to the HBR disk until servers become available.

For more information about HBR, see "Health-Based Routing (HBR) Session Agent" in the Unica Discover Configuration Manual.

Before you begin the upgrade, verify that the Data Collector completed its run.
