How to Migrate Joomla! 1.0.x to Joomla! 1.5.x?

I am still using Joomla 1.0.15 for one of my sites. Now I am thinking to upgrade it to Joomla! 1.5.x. The reason being is Joomla! 1.0.x is no longer supported. Also hackers can hack the older version of Joomla! easily. So it is time for me to move on. I know it is not easy but I have to do it...I will write down the steps along the way. Here they are...

• Backup all my files of Joomla! 1.0.15 to my desktop through FTP
• Login to my hosting cPanel
• Click on phpMyAdmin to export my database to my desktop
• Download Joomla! 1.5.24 from Download Joomla! to my desktop
• Download the Migrator component to my desktop
• Install the Migrator component to my existing Joomla! 1.0.15 site
• Login to my Joomla! 1.0.15 backend
• Click on Components/Migrator
• Then click on Create Migration SQL File
• Next click on Start Migration >>
• Then click on Download to save SQL Dump from my Joomla! 1.0.15 to my desktop
• Next make a clean Joomla 1.5.24 installation in a new folder for instance internet
• Then upload Joomla! 1.5.24 to http://www.mywebsite.com/internet
• Next type that url in my browser to run the installtion
• Then choose my language and click on Next
• Next check whether everything is okay if not it should be corrected and click on Next
• Then read GNU General Public License and click on Next
• Next go to my server and create a new database. Jot down the username and password for the next step.
• Then fill in Database Type, Host Name, Username, Password, and Database Name and click on Next
• Next fill in FTP user, FTP Password, FTP Root Path for FTP Configuration and click on Next
• Then for Main Configuration fill in Site Name, I leave Your Email, Admin Username, Admin Password, and Confirm Admin Password blank. 
• Next I have to tick next to the Load Migration Script option, fill in the old table prefix jos_, leave the Old Site Encoding the way it is, browse the Joomla 1.0.x migration dump that I downloaded earlier, tick next to This script is a Joomla! 1.0 migration script, and hit Upload and execute button
• Then I see "Migration successful. Press Next to continue". So I just click on Next
• Finally I have to remove installation folder
  

After that I find out my Joomla! 1.0.x theme is not compatible with Joomla! 1.5.x. Also my images, my favicon, all my components are gone. So I have to work hard to get them back.

P.S. I try to migrate to Joomla! 1.7.x directly but it will not allow me to do so. So instead I have to migrate to Joomla! 1.5.x instead. My next post will be How to Upgrade Joomla! 1.5.x to Joomla! 1.7.x. So stay tune for that...
