我去官方網站找到了解答，但是苦於英文程度不夠看不大懂怎使用。
是否有人可以給予指導一下呢??
以下是在FB官方網站看到的解答。

Upgrade

The best method to achive a smooth upgrade is as follow:


Do not Uninstall the component! Or you will loose your avatars and documents.
Install the new version on a local server (not your real site). just install a localserver, like easyphp, and install it there

backup you whole file system and database. Specially database!
Note down you configuration
Backup your templates directoy. In addition you have to edit the templates once again as the template CSSs are totally changed.

Overwrite the corresponding directories to the path on the server. Like: _Local_>components>com_fireboard to _SERVER_>components>fireboard
Run the upgrade SQL queries in the package. Go to your Cpanel->MySQL->PhpMyAdmin->SQL tab-> Modify jos_ to your prefix -> and hit run
Complete the final configuration by visiting the admin backend of Fireboard
Vola!

昨天才升級，把這篇稍微解釋一下

不建議移除後再安裝
升級檔建議先裝在其他電腦上，裝完之後在依照目錄所在位置移至覆蓋掉原先的1.0.0檔

而sql檔案的升級就需要使用phpMyadmin來操作
如果你租用虛擬主機，可以依照指示的路徑Cpanel->MySQL->PhpMyAdmin

進入phpMyadmin後，選擇jos_的資料庫(即是fireboard所在資料庫)
點選上方SQL tab，之後會出現一個空白區
把你引用的文字剪貼進去，然後執行(便是執行sql指令)

這樣就完成sql與程式的升級了
