As you pair new devices, keep an eye for “ghost” notes on the Z-Wave details screen. They will occur when a device has trouble pairing and will quickly cause havoc on your mesh. Remove them right away - this will require you to power-off the device that caused them / that you had trouble pairing, or will require you use a UZB-stick.
If you decide you want your Zooz 4-in-1 on the C-7, be sure to pair them with no security using a UZB stick. I bought one at Mouser.com shortly after I completed my transition. I wish I had ordered it before... The price is quite reasonable for the amount of time it saves! (I now have all my Zooz 4-in-1 sensors on my C-7 with no security and it seems to work well.)
I decided to go the back-up / restore route following instructions from the following awesome post:
To make the transition easier, I made a spreadsheet with all my Z-Wave devices (using a copy from the Z-Wave Detaisl screen). It allowed me to ensure all my devices were properly transitioned.
I also did a spreadsheet of all issues I encountered to help me troubleshoot and ensure I fixed everything.
Finally, the community was really awesome during the transition... I went from a super-stable mesh to one with multiple issues (due to ghost nodes, Zooz devices, etc.). A few days after those issues were fixed with lots of help from the community, the mesh stabilized and now things are back to normal.
Oh, and be sure you have your 2-day weekend to dedicate to this, and warn your family (as applicable), that things will not be working right for up to a couple of weeks.
It is a lot of work, but really worthwhile. There are some really nice new features with the 700 chip, mostly things you can see and do from the Z-Wave Details screen.
