Vertica adds new features and enhances existing features with every release. To access the new and improved features, upgrade to the latest release of Vertica.
Before you upgrade, perform the following:
Vertica recommends you to upgrade to the immediate next version for best performance results. For example: Upgrade to the next incremental version of Vertica. For example, upgrade from 7.1 to 7.2 or 8.0 to 8.1. For more information, see Upgrade Paths in the Vertica documentation.
After you complete these tasks, shut down the database and follow these steps:
|1||Perform a full local backup of your existing database and stop the database.
||If the backup is successful, proceed to Step 2.
If the backup is not successful, see Creating Full Backups in the Vertica documentation.
|2|| Uninstall any additional packages that you installed on each host.
If you omit this step and do not uninstall additional packages, the Vertica server package fails to install in the next step.
|If the uninstall is successful, proceed to Step 3.
If the uninstall is not successful, examine the error and contact Vertica technical support.
|3||Install the new Vertica Server package on any host as root or sudo.
You can install on one node or all the nodes. If you install one node at a time, the install_vertica script installs in other nodes sequentially. If you install all the nodes at the same time, the install_vertica script is faster as the script does not have to copy the rpm.
|If the install is successful, proceed to Step 4.
If the install is not successful, examine the error and contact Vertica technical support.
|4||Run the update_vertica script as root or sudo, as shown in the following sample command:
||If the update is successful, proceed to Step 5.|
|5|| Start the database.
||When the database starts, proceed to Step 6.|
|6||After upgrading the Vertica server package on your cluster, upgrade the client authentication.
If the upgrade is successful, proceed to Step 7.
If the upgrade is unsuccessful, contact Vertica Technical Support.
|7||Reinstall the packages that you uninstalled before upgrading. For each package, see its install or upgrade instructions.||If the upgrade was unable to install one or more packages, reinstall them with admintools.|
