Any benefit to use Protection Plan EU C5 to C7?

I just found out that a C5 to C7 migration can't be done for the C5 EU hub because of the external Z-Wave radio stick.
Is there any benefit to then use the protection plan for the migration or is a local backup and restore just as good? As I understand I can restore a backup and then include all ZigBee devices and they will be added with the right ID, name etc. again. I have to redo all Z-Wave devices and rules anyway.

But maybe, and I hope so, its better and makes the migration smoother through the Protection Plan anyway...
