Is there any recommended way that need to be followed for applying a new patch to the OpenStack service (like nova, neutron...) without downtime?

Basically impossible AFAIK except you have the HA backup.

Thanks for your response Xiangfei! What are the possibilities for HA setup to apply the patch?

I mean if you have the HA setup, then you might be capable of applying the patch by the following steps:
1. apply the patch to standing-by node firstly
2. after that, switch the acting<--->standing-by nodes' status
3. apply the patch to new standing-by node
to avoid the down time.
