After you upgrade
After you finish upgrading the Vertica server package on your cluster, a number of tasks remain.
Required tasks
- 
If you created projections in earlier releases with pre-aggregated data (for example, LAPs and TopK projections) and the projections were partitioned with a GROUP BY clause, you must rebuild these projections. 
- 
Verify on each node that the upgrade reduced database catalog memory usage. 
- 
Verify your database retained the grants from before you upgraded. See Backing up and restoring grants for more information. 
- 
Reinstall packages such as the R language pack that you uninstalled before upgrading. For each package, see its install/upgrade instructions. NoteVertica Place is automatically reinstalled with the Vertica server package.
- 
If the upgrade was unable to install one or more packages, reinstall them with admintools. 
- 
If your Vertica installation is integrated with Hadoop, upgrade the HCatalog connector. 
Optional tasks
- 
Import directed queries that you exported from the previous version. For details, see Batch query plan export and Managing directed queries. 
- 
If you're upgrading from Vertica 9.2.x and have set the PasswordMinCharChangeorPasswordMinLifeTimesystem-level security parameters, set them again at the PROFILE-level.
