Splunk Enterprise 9.0 fixes a critical vulnerability in deployment server but might introduce problems for older deployment clients

If you run a deployment server, upgrade that server to version 9.0 of Splunk Enterprise as soon as possible. Before the upgrade, carefully review your deployment server setup and the current versions of the deployment clients in your Splunk Enterprise network. Depending on the setup of your deployment server and whether that component shares a computer with other Splunk Enterprise components, you might need to do the following to ensure your deployment server and clients communicate without problems:

• Isolate deployment server from other components on a machine. Isolating your deployment server means you only have to upgrade that component. The sole exception for isolation is if you run a deployment server and a license manager on the same machine.
• Confirm that all deployment clients in your network run version 7.0.0 or higher of Splunk Enterprise or the universal forwarder. You don't have to upgrade deployment clients to version 9.0.0, but they must be at version 7.0.0 or higher to communicate with version 9.0.0 deployment servers.
