Updating from Norton 360, 5 device [Multi-Device] - Identity Safe?

I'm about to update from Norton 360, 5 device to Norton Security 2015 and I just found out that the NS 2015 does include Identity Safe. My question is if I purchase or download NS 2015 from a vendor other than directly from Symantec, will I be able to keep or maintain my Identity Safe log-ins and such? Additionally, am I correct in assuming that w/the purchase of NS 2015 - 5 Devices I'll be able add my android devices?
