Before you begin, verify that you have completed the items listed in the checklist
documented here.
Procedure
- Reviewed the overall process. See Overview of the Upgrade Process.
-
Reviewed the changes to Discover.
- Completed the preparation steps. See Preparing to Upgrade to the Current Release.
-
Copied Discover software to each server. For every server that you are
upgrading, copy the Discover software to a directory outside of the Discover installation directory.
-
Backed up the server. You should perform a backup of all Discover
directories and SQL Server databases on the server before you begin the upgrade of it.
- Ideally, you should create a complete mirror image of the server.
- Stopped traffic and allowed Data Collector finish: Immediately
before upgrade, you must stop traffic to the Processing Servers in
your environment and allow the Data Collector to complete its collection
run from the stopped Canisters. See Preparing to Upgrade to the Current Release.

You should also know the process for upgrading an individual server, whether you are upgrading
only the current components or changing the configuration. See Upgrading Discover Software on a Server.
