Before You Upgrade
Before you upgrade the Vertica database, you must perform the following steps:
- Perform a full database backup. This precautionary measure allows you to restore the current version, if the upgrade is unsuccessful.
- Verify platform requirements for the new version.
- Check catalog storage space.
- Uninstall the HDFS connector (required only if you are upgrading from pre-7.2 versions).
- Back up any Geospatial indexes and save the results in a temporary table.
After you complete these tasks, shut down the database gracefully. This procedure is described in the Administrator's Guide: Stopping the Database.
