Before you begin the upgrade, you must complete the prerequisites to back up and save your existing environment.
Verify that your source installation is fully installed and configured.
Back up the vRealize Appliance configuration files in the following directories, for each instance of the appliance.
Back up all databases.
Create a snapshot of your tenant configuration and the users assigned.
Back up all files that you have customized on Windows or Linux/UNIX. For example, on Windows, back up: C:\Program Files (x86)\VMware\vCAC\Server\Website\XmlData\DataCenterLocations.xml
Create a snapshot of your virtual appliance, and adhere to regular guidelines for backing up the entire system in case the vRealize Automation upgrade fails. See Configuring vRealize Suite 6.0 for Backup and Restore topics in vRealize Suite documentation.
