I want to upgrade my Pentaho BI Server CE from 6.0 to 8.0 but I can't find any step by step instructions. Can anyone please help me? I've downloaded the pentaho-server-ce-22.214.171.124-28.zip file and extracted it to my server, alongside the current instalation (on different folders). Now I have no idea what to do next. What folders and files should I backup?
Any help will be appreciated.
