I just finished my migration from C5 to C7 using @bravenel 's Migrating a Z-Wave Network as the guide. (Hat tip to @JonhRob for his simple breakdown Migrating a Z-Wave Network - #102 by JohnRob)
After a false start (hint: you need to change ALL of the DNI's. You can't "test" the process with one device), it went very smoothly.
25 Zwave devices took me a couple of hours to migrate over. Having a laptop to walk around the house made this a lot easier than running up and down stairs to get to a desktop.
Felt tedious to start and after a few devices built up some (false) confidence, it moved very quickly. That said, I sure do wish there were a better way that didn't cost $120 to move to my new $100 C7 impulse buy.
