Upgrading Splunk Enterprise 7.2 to 7.3

Hello, All of our indexers our on Splunk Cloud, but we have a deployment server that acts as a forwarder for all of our windows servers, and has Splunk Enterprise 7.2.4.2. We need to get this updated to 7.3. My question is this: Is it just as simple as running the 7.3 installer and letting the installer do it's thing, or do I need to do any steps before to make sure this runs smoothly? Thanks in advance, Bob
