• We don't want to run installer just to do maintenance, which could potentially leads to error and causes the AAP error.
• We prefer to have a specific script/playbook to these kind of tasks for maintenance.
• We would like to have do the maintenance on specific nodes only, for HA purpose.

We wants to request a feature where :
WE have a mechanism to do individual maintenance activities without running the entire installer.
An EXAMPLE is, if tomorrow, they need to replace their existing SSL certs, then they should be able to do it separately without running the entire installer and avoiding downtimes/maintenance windows. (only renew SSL cert)
Similarly any maintenance activities can be done without downtime or the use of running the entire installer; instead sticking to a procedure which only change the intended.
So, maintenance / renew SSL cert on specific node. (e.g HA set of controller, eda ,hub, gateway), when we update something, we update the 2nd node first, and once it is success then only we will update the 1st node.
