Questions before ZCM11.2.3a upgrade

Hi,

After my first primary is upgraded from 11.2 to 11.2.3a following the installation procedure.

How do I upgrade my second primary server? Via assigning the 11.2.3a update in ZCC - Configuration - System updates?

Or do I have to update my second primary with the zip file and the installation procedure?

What about the sattelites? Also assign it via System updates in ZCC?

This means that the 2.3 gb from the update has to replicate from the primaries to the satellites servers? This will take some time in my case, is that a problem?

Thanks in advance.
