I've copied my live website to my localhost for migrating into higher version. The problem that has been arises is that my menus and components are not opening and it's saying that it does not found any articles and components that has been assigned to menu. So i just want to know that if i will upgrade my joomla website which is currently has 1.5.26 version to 2.5 then will it effect on my website when i will upload it later on after migrating into higher version. Will everything will gonna work fine or still having a htaccess issues or not?
