Smartest way to move iTunes library to external drive?

[morningsong]

Currently I have about a 200gb iTunes library (music, movies and TV).
I'd like to move all of those files, and all new media to an external drive.
I've purchased two, 1 TB external drives in hopes of somehow mirroring one drive so there's no catastrophic failure and wind up with nothing.

So, the question is, in order to keep everything organized...
Do you copy the current media to the external drive first and then delete what is on the iMac hard drive?
Uncheck the 'copy files to iTunes Media folder' in iTunes prefs, and then start to populate the music, movie and TV shows back into iTunes.
Those are the correct steps, yes?

Also, is there a way to either mirror one external to the other, or time machine one external to another? I already have a drive doing TM b/u and it is nearly full.

Any advice is greatly appreciated.
Thanks!

To move your iTunes library, simply :

1. Copy the entire iTunes folder (/Users/YourUserName/Music/iTunes usually) to the new drive.

2. Open iTunes while holding the option key and pick "Choose Library", and choose the iTunes folder on the new drive.

To mirror one drive to another you can use Carbon Copy Cloner

Hmm.

What's interesting is that I tried this today and my Apps and Books did not copy over. Everything else seems good to go.

Why wouldn't apps and books copy over?

Thnx
