My standard rsync options are -avPp - I've been doing it that way so
long I cannot recall what they each do, but I get progress reported
back to me!

I assume you are doing rsync over your lan. It may be quicker to
remove the storage drives from the old machine and plug them in to the
new machine. The transfer will be quicker, and you can still use rsync
so that if you have to stop for some reason, you can carry on later.
