Do we have a way to manage the agents from one endpoint to another endpoint manually?
e.g. agents are connected to 2 x security gateways and now I want to upgrade one of the gateway or the server but before that I should be able to move all the connected agents to another security gateway for doing the scheduled activity.

I did a quick check in my lab and the failover took approximately 40 seconds. No data was lost (agents have buffer for data).
Just a quick note - there are multiple connections from monitored host to the gateway. Each instrumented app has its own one, os agent, plugin engine and log analytics also have individual connections. Its normal to see that agent parts or instrumented applications report to different endpoints at the same time.
Buffers are sized in bytes. So the duration how long agents keep data depend on how much data the agent sends.

Yes, the agent buffers data only in memory, not on disk.
The failover should happen within 10 seconds + the time it takes to establish a new TCP connection (it happens on every heartbeat, which has a 10 sec interval).
Babar, Julius's answers seem to address your questions. Can you clarify what additional understanding you are needing? Be sure to explain your use case so we understand your context of questions.
Hello @Joseph M. H.
Please consider my apologies in advance in case I am asking something weird.
Basically I am trying to collect the maximum technical information to complete the TDD.
Do we have an upper memory settings for the agent to buffer the data or it will use the host memory without any limitation?
