Upgrading Vertica
Upgrading your database with a new version includes the following steps:
Starting with Vertica 12.0.x, you can upgrade from your current version directly to the latest version, skipping the interim versions. Before upgrading, make sure that you have performed a full database backup and have tested the new version in an environment that closely resembles your production database.
Tip
If you want to test out a new version of OpenText™ Analytics Database for an Eon Mode database without spinning up a new cluster, you can sandbox a secondary subcluster and then upgrade the subcluster within the sandbox. By sandboxing the subcluster, you can try out the new database version stress-free and continue to use your main cluster as usual. After confirming that the upgrade works and performs as expected, you can downgrade the sandboxed subcluster, remove the sandbox, and proceed to upgrade the main cluster.Be sure to read the Release Notes and New Features for the database version to which you intend to upgrade. Documentation and release notes for the current version are available in the RPM and at https://docs.vertica.com/latest, which also provides access to documentation for earlier versions.
For guidance on upgrading from unsupported versions, contact Vertica Technical Support.
