The procedures in this chapter guide you through upgrading the Sentinel.
You can upgrade from Sentinel 8.2 or later.
The upgrade process does the following:
Migrates Security Intelligence data and alerts data from MongoDB to PostgreSQL.
Sentinel now stores Security Intelligence data, alerts data, and so on in PostgreSQL instead of MongoDB. The upgrade process will first migrate this data to PostgreSQL and if successful, will automatically proceed with the upgrade. If the data migration is unsuccessful, you cannot upgrade Sentinel.
Generates a cleanup script that you can use to remove data and MongoDB related RPMs from MongoDB.
The data stored in MongoDB is retained as a backup.
