Nis2014 to ns2015 and retain local vault

i have win7 64bit and winxp 32bit running nis2014 with local vault. i have a norton account.  i purchased ns2015 from amazon boxed with product key. instructions on card from box states   1. go to norton .com/setup    2. enter product key   3. click next and follow the prompts.    i assume this is an over the top install and will i be able to keep my local vault and decline the online vault?   thanks for your help. i need to do this in the next 7 days
