In your customer portal, you will find upgrade packages specifically designed for your additional polling engines. When you click on 'choose download' you will be taken to a screen that breaks down each component for installation, and also will have an 'all-in-one' package.
Make sure you plan this out before your change window occurs as upgrade paths vary for everyone based on what you have licensed. Don't be afraid to open a quick ticket to tech support for the 'official' upgrade path, or you can check out this link: SolarWinds Knowledge Base :: Compatibility of SolarWinds Orion Products for Installation and Upgrade
To more pointedly answer your question, yes. You will want to upgrade your primary engine before your additional pollers. With the exception of items like IPAM and VMAN-integration, which are installed only on the primary server.
