no, The only internal implant that can upgrade to Nucleus 5 is Freedom implants. Any implants older than that (I think 2005) can only upgrade to Freedom.
The first thing is get an appointment for second ear implant. go cochlear.com website and search up the nearest CI clinic (click on the "Find a clinic") so you can make an appointment. They will guide you from there. You probably need to do that anyway if you want an upgrade.
