I am looking to update a PRTG core server and over 10 remote probes. Does this update require a reboot? How do the remote probes get the update, and where do I see if they actually updated/current version of the probes?
Whether or not an update it necessary or not is impossible to predict. If there are logged system files, a restart is most likely and also from my perspective I recommend a clean restart once an update of PRTG was been done.
Remote probes will usually receive the update files directly from the PRTG core server and automatically update itself to the latest version.
Further information on this process can be found here. It's quite visible if a remote probe requires an update or not. If the remote probe is not running the same version as the PRTG core server, the probe will not successfully connect to it and state that a manual update is required. You will see this in the interface of PRTG. Also, for more information check the above linked article.
