Upgrade LiveCache version

Hello,

There is a new SCM 5.0 SP stack and therefore a new patch version for the livecache.

So i'll be upgrading from 7.6.03(SP14) to 7.6.04(SP15). I was wondering which option i have to choose in the SDBSETUP ... I have three options:

1° Install DB+software

2° upgrade DB+software

3° upgrade only software

Which one do i have to choose ?
