Before upgrading the gateway, the PAPIM agent was installed. The steps to backup the gateway were followed as described in the documentation. When trying to perform a restoration on new gateway, as described in the Post Upgrade tasks, an error was encountered. The chkconfig --add epagent command returns an error: Unknown option: add
API Gateway 11.x
Gateway 11 is using Debian as an OS and chkconfig --add does not exist on a Debian system. The command to add the epagent to the startup should look like this:
chkconfig [ --level levels ] service <on|off>
or
systemctl enable <service_name>
