Thank you all so much for you council and advice. I have decided to try Roon and so far, I am very impressed. It ate up that huge library and was ready to go in about 2 hours. It was so easy to set up I was amazed. I had heard about Roon and how much it can do, I incorrectly thought I had to be really networking savvy. Nope, Roon did it all for me.
As for this huge library, I appreciate the advice regarding backing it up! I do! I actually have 2 physical back ups stored at 2 different locations.
Thanks for your help!
Let's go listen to music!
