Thanks, yeah we had to request an unlock. I assumed they were unlocked already since they were bought on Apple's iPhone Upgrade program but I guess maybe that's not the case since we chose the model with the AT&T specific SIM vs buying a specifically "unlocked" model like I did with my 6s+ originally. I'm going to do the backup/restore this weekend.
I've been wanting to test the difference between local secure and iTunes restore with all the iCloud changes in the last couple OS versions anway so I'll do a secure local backup and then do the process and try an iCloud restore first to see if my passwords/health data/etc. come down now or if secure backup restore on iTunes (PC user) is still needed.
