Norton 360 & Norton 360 Multi-Device Renewal

I have Norton 360 Multi-Device for 5 PCs and also Norton 360 for 3 PCs.  The Multi-Device for 5 seats was expiring and was automatically renewed at $89.99.  The Norton 360 for 3 PCs will be expiring soon (don't have this on auto renewal), but the renewal cost is also $89.99.  There seems to be a new Norton Security & Backup now available for up to 10 devices at $69.99 for a 1-yr subscription.  Would I be able to transfer all of my 8 PCs over to a new Norton Security for $69.99 for 1 year?
