551918 Update Joomla 1.0 to Joomla 2.5

I have a joomla 1.0 website that needs to be updated to joomla 2.5 and to make sure that the extensions and templates are working. It should be backed up before work begins. extensions: ** jcal pro is currently on the website - drop this and install jevents 2.5 silver instead [login to view URL] ** install: JCE Administration- [login to view URL] ** install: RokGallery Module [login to view URL] [login to view URL] **Ninja RSS Syndicator: [Feed manager] - if it doesn't work find a comparable one. Some extensions may not be able to update, let me know. I'm willing to let them drop.
