Norton 360 ....I have but do I need to upg to N Internet Security

I am a long-term user of Norton 360 and I keep using liveupdate and auto paying an update fee yearly,   However, I think I have lost
track of the product family; it has been a LONG time since I looked at the product family......is Norton 360 Premier Edition still an active product....I have this installed on 5 computers and I have auto charge for the yearly update fee.   But I can't seem to find the product on the active products list.   Do I need to transition to Norton Internet Security and is there a migration path.....Liveupdate just seems to add patches and updates to Norton 360.  Do I need to buy a new product.....is Norton 360 going away or is it just a matter of knowing how to migrate with everything I have in place.    I am having no problems with Norton 360 Premier Edition that I know of.  Thank you in advance for your response.
