I followed the instructions step by step after connecting all the external disk drives to the new Mac mini and making all the necessary connections, and I was ready to start up Plex.

The new one is on the left.
But I hesitated.
The only previous time I had moved Plex was when I moved it from my desktop to the Mac mini and the library was much smaller then. Now it had many terabytes of data.
Still, I had moved the original disk drives or made exact copies of them, so from Plex’s point of view, all the video files were in the same places.
I held my breath and started up Plex.
To my great relief, Plex seemed to find everything without any problems. A few tweaks were needed. In order for Plex to handle remote connections, I needed to disable remote connections and start them up again because Plex was now running on a different system, but that was easy enough.
I sent a note to my sister to see if she could access it. She could.
Operation complete, as far as I was concerned.
Meanwhile, the Met Opera broadcast on Saturday afternoon was Richard Wagner’s Tristan und Isolde, one of my favorites, and it was conducted by Yannick. I streamed it off WRTI’s web site and captured it with Audio Hijack for later listening.
Here’s a taste. The Prelude to Act II, which is lovely music but is never played as a concert piece because it’s too short and doesn’t really have an ending.
