Backup your existing system
It is always worth backing up an existing deployment so that you can revert changes if needed.
Stop Services and Processes
To swap new upgraded libraries, you must stop any running processes.
The new version of AIOps is installed via the new RPMs and you must make changes to config files.
Upgrade the Db
You must upgrade the schema and data within the Db between releases.
Upgrade Apache-Tomcat webapps
Deploy the new Apache-Tomcat servlets.
Restart Services and Processes
You must restart all the processes before running the new version of AIOps.
Verification of upgrade
Run verification scripts to ensure the upgrade was successful.
