身為一個非軟體工程師，即使不懂得如何用terminal寫command，也可以學會如何用Google來學習！
前陣子升級Joomla 1.6 to 2.5的過程，整理出來一個To Do List (with my note)和大家分享：
- Recommended Step: Back Up Usually your hosting company will make periodic database back ups for you. So I actually risked and skipped this…!
- Upgrade Instruction http://docs.joomla.org/J2.5:Upgrading_from_an_existing_version#tab=Overview
- I used “Method B” since for some reason the update function within Joomla admin didsn’t work on that specific server. I couldn’t upload via Extension Manager either. So I had to FTP the package and install from the URL.
- DO NOT FORGET TO DO: Database Upgrade
- To avoid such issues: template problem, user database problem, etc.
- How to: Extention Manager > Database > Fix
