The consolidated vRealize Automation Installation Wizard is your primary tool for new vRealize Automation installations. Alternatively, you might want to perform the manual, separate installation processes in some cases.
The Installation Wizard provides a simple and fast way to install, from minimal deployments to distributed enterprise deployments with or without load balancers. Most users run the Installation Wizard.
You need the manual installation steps if you want to expand a vRealize Automation deployment or if the Installation Wizard stopped for any reason.
Once you begin a manual installation, you cannot go back and run the Installation Wizard.
