Not sure if the question refers to a production environment or complete landscape. Assuming it is for landscape (DEV-->QAS-->PRD) and may be you have Sandbox or POC kind of system, then start with this system to see any side effects of patches.


From technical perspective below if the high level upgrade steps:

1. Stop all communication channels, Business process engine, background Jobs. Interfaces should be stooped so if there is any system which may try to push data to PI , then that system should be handled so that that push is not attempted.

2. Use SUM to apply patches.

3. Once SUM is finished, make preliminary system check.

4. Reverse the step 1. Bring everything back up.

5. PI and Business tests needs to be done to verify all interfaces are working.
