ETCNet3 Planning Guide ?

We are looking to replace our aging Obsession II / Net2 systems with ION consoles, and I was looking to see if there was a NET3 overview document like there was for Net2.  (ETCNet2 Planning Guide v4).  I did a lot of searches on the ETC website, but didn't really find a similar document.  If anyone is aware of one, please let me know where I can find it!

Many Thanks,

Tom
