Prerequisites: The person following these steps should have good knowledge of Linux shell scripting and must log in with SUDO privileges.
Recommended: The update process automatically creates a backup, but we strongly recommend creating a manual backup of eRS database, before proceeding.
1. Install the XML utility
Check if `xmllint` is already installed
xmllint --version
If the above command says 'xmllint not found', install using the default package manager (apt or yum)
sudo apt install libxml2-utils
2. Change user context to "eRS"
sudo -su ers
cd /opt/ers
3. Execute the update-script
./update.sh
To ensure that you have updated to the latest version, re-run the update script.
./update.sh
4. Finally, restart the service
Exit to the sudo user context and restart ers service
exit
sudo systemctl restart ers
