Supported upgrade paths

You can upgrade to Discovery Accelerator 10.0.1 from the following versions only:

• Discovery Accelerator 8.0 SP5
• Discovery Accelerator 9.0.3
• Discovery Accelerator 10.0 original release

For the latest information on supported upgrade paths, see the technical note called Supported upgrade paths for Enterprise Vault, Compliance Accelerator, and Discovery Accelerator (http://www.symantec.com/docs/TECH53174).

Supported versions of Enterprise Vault in Discovery Accelerator environments

If you install the Discovery Accelerator server software on a separate server from your normal Enterprise Vault installation, you must install the Enterprise Vault software on the Discovery Accelerator server. As a minimum, you require a 9.0 or 10.0 version of one of the following:

• Enterprise Vault Services
• Enterprise Vault API Runtime

Note the following important points about the version of Enterprise Vault that you install on the Discovery Accelerator server:

• All Enterprise Vault servers in all Enterprise Vault sites in a Discovery Accelerator environment must run the same version of Enterprise Vault. For example, when using Discovery Accelerator with two Enterprise Vault installations, you cannot have one site that runs Enterprise Vault 9.0 and another that runs Enterprise Vault 10.0.

• The major version of Discovery Accelerator must be the same as, or one later than, the major version of Enterprise Vault. For example, you can run Discovery Accelerator 10.0 with Enterprise Vault 9.0 servers, but you cannot run Discovery Accelerator 9.0 with Enterprise Vault 10.0 servers.

• If the major version of Discovery Accelerator is the same as the major version of Enterprise Vault, the minor version (Service Pack) of Discovery Accelerator must be the same as, or later than, the minor version of Enterprise Vault. For example, you can run Discovery Accelerator 10.0.1 with Enterprise Vault 10.0.0 servers, but you cannot run Discovery Accelerator 10.0.0 with Enterprise Vault 10.0.1.

See the Compatibility Charts for more information about supported versions.

Before you begin

Before you upgrade to Discovery Accelerator 10.0.1, we recommend that you do the following:

• Check for and stop any active searches, export runs, and production runs. In the following article on the Symantec Enterprise Support site, steps 4 and 6 provide SQL scripts with which you can check for these operations:

  http://www.symantec.com/docs/TECH63230

• Check for searches that have a status of either "Pending Acceptance" or "Pending Acceptance (with errors)", and accept or reject them. In the above article on the Symantec Enterprise Support site, step 5 provides a SQL script with which you can check for these searches. By accepting or rejecting the searches, you can reduce the amount of data that the upgrade procedure must process.

• Check the tblSearchResults table of the Discovery Accelerator customer database for rows that have been left over by searches that you have already accepted or rejected. To do this, run the following SQL query against the customer database:

  SELECT COUNT(*) FROM tblSearchResults

  If the query returns any result other than 0, and no searches are currently running, then you must clear the table of invalid data before you proceed. Contact the Symantec Support team for assistance.

• On the Discovery Accelerator server, use the Services snap-in to Microsoft Management Console to stop the Enterprise Vault Accelerator Manager service. This service can interfere with the upgrade process if you leave it running.

• Use the facilities in SQL Server Management Studio to do the following:

  • Make a backup copy of your Discovery Accelerator database and transaction log.
  • Truncate the transaction log.
  • Enable autogrowth for the database and transaction log in fixed increments of 250 megabytes.

  Consult the documentation that accompanies SQL Server Management Studio for instructions on how to perform these activities.

• If you use Microsoft SQL Server database mirroring with your Discovery Accelerator databases, remove it before you upgrade the Discovery Accelerator server software. Discovery Accelerator fails to upgrade its databases if mirroring is configured. For more information, see the following article on the Symantec Enterprise Support site:

  http://www.symantec.com/docs/TECH64763

• Ensure that the drive hosting the transaction log has available space that is equal to or greater than four times the size of the database.

• Disable the following features on the Discovery Accelerator server, Enterprise Vault servers, and all SQL Servers that host an Enterprise Vault database or Discovery Accelerator database:

  • Receive-Side Scaling
  • TCP Chimney
  • TCP/IP Offload Engine
  • TCP Segmentation Offloading

  Article TECH63230 on the Symantec Enterprise Support site provides instructions on how to disable these features.

• Disable any Network Interface Card (NIC) Teaming that may be present on the Enterprise Vault and Discovery Accelerator servers. For guidelines on how to do this, consult the documentation that your hardware vendor provides.

Steps to upgrade your Discovery Accelerator system

Upgrading a Discovery Accelerator database that contains millions of items can take several hours to complete. During the upgrade process there are several pauses that may give you the impression that it has stopped prematurely. We recommend that you perform the upgrade at a quiet time and allow it to run through to completion. Ideally, seek the assistance of Symantec Consulting Services when upgrading.

See the Installation Guide for more information on how to perform the following steps.

To upgrade your system to Discovery Accelerator 10.0.1

1. Log on to the Discovery Accelerator server as the Vault Service account.

2. If you have also upgraded your Enterprise Vault environment, upgrade the Enterprise Vault components on your Discovery Accelerator server to match the other Enterprise Vault servers in the site.

   See the documentation that accompanies Enterprise Vault for guidelines on how to upgrade it.

3. Start the Discovery Accelerator server installation program (Symantec Enterprise Vault Discovery Accelerator Server_language.msi).
4. Follow the on-screen instructions.
5. When the installation process has completed, open the Accelerator Manager Web site (typically, http://server_name/EVBAAdmin).
6. Click Update to update the configuration database.

7. IMPORTANT Follow the on-screen instructions to restart the Enterprise Vault Accelerator Manager service. You can use the Services snap-in to Microsoft Management Console to do this.

   Do not skip this step, as you may experience problems if you do.

8. In the Accelerator Manager Web site, click OK.
9. Click Upload License to import your license key file for Discovery Accelerator 10.0.1.

10. To upgrade each customer database, follow these steps:

    1. In the left pane of the Accelerator Manager Web site, right-click the name of the customer database and then click Properties.
    2. In the Customer dialog box, click Upgrade.
    3. Monitor the upgrade progress until it has completed and the customer status is Running.

11. Use the Accelerator Manager Web site to re-upload the Discovery Accelerator report templates to your SQL reporting server.

    Discovery Accelerator 10.0.1 includes some updates to existing report templates. To make the updated templates available, you must upload them to your reporting server.

12. If you have not previously done so, use the Accelerator Manager Web site to set up Custodian Manager.

    Custodian Manager is a browser-based application with which you can store the details of the "custodians" (individual employees) and custodian groups for which you want to search with Discovery Accelerator. A custodian group is any collection of employees, such as Windows or Domino groups and distribution lists, Active Directory or Domino LDAP searches, and Active Directory containers. After you have added the custodians and custodian groups to Custodian Manager, you can pick from them when you define the criteria for a Discovery Accelerator search.

    To set up Custodian Manager, follow these steps:

    1. In the left pane of the Accelerator Manager Web site, right-click the server node and then click New Customer.
    2. In the Create Customer page, set the customer type to Custodian Manager.

    3. Enter your preferred IIS and SQL database details, and then click OK.

       Use the online Help to assist you, if necessary.

13. Install the Discovery Accelerator client software on the computer of each user who will be running the client. The Discovery Accelerator release media include two packages with which you can install the client software on your users' computers:

    • A standard Windows Installer (.msi) package.
    • A ClickOnce installation package. ClickOnce is a Microsoft technology that lets users install a Windows application by clicking a link in a Web page.

    One advantage of using the MSI installer package is that it lets you install the client software on a per-user or per-machine basis, whereas ClickOnce installations are on a per-user basis only. On the other hand, ClickOnce provides the ease of deployment of Web applications and makes it simple to distribute updates to the Discovery Accelerator client.

    IMPORTANT The version of the client software that you install on your users' computers must exactly match that of the Discovery Accelerator server software on the Discovery Accelerator server.
