Install, Upgrade and Uninstall Arcserve RHA › Upgrade an Installation

Upgrade an Installation

Although Arcserve RHA is different from the previous version in many respects, there is no major difference between a new installation and an update to an existing one. The system automatically detects previous components, and the MSI wizard carries out all the required tasks to upgrade the application. You can import existing scenarios and reuse them through the Arcserve RHA Manager.

Important! Full System scenario must be re-run at least once after you upgrade to r16.0 SP2 or later from a previous release.

Note: The scenarios that were created in the previous version were saved by default in INSTALLDIR:\Program Files\CA\Arcserve RHA\ws_scenarios. For more information about the import process, see Arcserve RHA Administration Guide.

For a successful upgrade, the only component you need to remove is the previous Arcserve RHA Engine. Therefore, you need to uninstall Arcserve RHA from each Master and Replica server. You can either use the Setup.exe file to automate this procedure or you can do it manually before you start the new installation.

Note: If you are trying to install the Control Service on a machine that contains a GUI from a previous version, you will get the following message:

A previous version of Arcserve RHA has been detected. You don't need to remove it in order to install the new version.

Click OK, and continue the installation.

To remove a former Engine using the setup.exe file:

1. Double-click the Setup.exe installation file. The Arcserve RHA Installation wizard appears.
2. Click the Install option. The Install Components page appears.
3. Click the Install Arcserve RHA Engine option. Click the Install Arcserve RHA Engine option.

   The Choose Setup Language dialog appears.

4. Select from the drop-down list the Installation wizard language you prefer, and click OK.

   A progress bar appears.

5. Once the initial process is completed, the Welcome page appears.
6. Click Next. The system detects that an old Engine exists on your server, and the Information about previous version page appears.
7. To automatically remove the older Engine, click Next. A progress bar appears.
8. Once the removal process is completed, the License Agreement page appears.
9. Follow the wizard's instructions until the installation is complete, as described on Installing the Arcserve RHA Engine.

Note: All existing bookmarks and rewind points are lost after the upgrade.

Upgrade in Phases

This release of Arcserve RHA is backwards compatible with the previous version, so you can upgrade over time.

To run Arcserve RHA in a mixed environment, consider the following:

• Upgrade the Control Service first.
• If you are not planning to upgrade the Master and Replica servers at once, make sure you upgrade the Master before the Replica. Backward replication is not supported until both servers are upgraded.
• For HA scenarios, you must upgrade Master and Replica servers at once.
• You cannot create new File Server or application scenarios when the running an older version of the Engine, but may create new CD scenarios.
