Upgrading the Prysm Eth2 client from binaries

The tl;dr for this is: yes, you can just upgrade Prysm by stopping your services, copying the new binaries and then restarting your services.

If one of these applications is especially greedy with regards to the routes/URLs it wants to control, then it can become a tricky project. Using subdomains can often help, as the subdomain can explicitly address the other application. However, if you need content from both applications under the same domain, and you don’t have access to or the desire to fumble with the routing (e.
