我需要升級Joomla！ 1.7.2穩定到2.5（它是一個活的網站）升級Joomla！ 1.7.2穩定到2.5
我的一些疑惑的是
Does the design changes back to the original default one.If so how can i recover it back?
Are there any good blog to refer its step by step process?
Are there any extension manager to do it with less error and quickly?
Jomsocial 2.4 is installed in it, does upgrading Joomla 2.5 will affect the files in
Jomsocial,because I have done some updations in these files(in components/com_community
and components/com_users)
