Updating Joomla 1.0.x and 1.5.x
The method for updating Joomla series 1.0.x and 1.5.x is the same, the only difference is the file that you use for updating. With both you can choose to use a Patch or the full installation zip/tar.bz2/tar.gz to update. Our preference is to update Joomla using the full installation package and omit the installation folder when uploading the files.
Make a backup of your site.
Download the correct file for your Joomla
Joomla_1.0.15-Stable-Full_Package
Joomla_1.5.25-Stable-Full_Package
Unzip the files and ftp all except the /installation folder to the server. The method to Update Joomla is exactly the same as the one used to Replace corrupt files.
Updating versions of Joomla between 1.6.0 and 1.6.4
To update versions of Joomla between 1.6.0 and 1.6.4 use the same method as described for Updating Joomla 1.0.x and 1.5.x. The file to use for updating in this instance is
Joomla_1.6.5-Stable-Full_Package.zip
Updating versions of Joomla 1.6.5 to 1.6.6 and 1.7.0
The introduction of Joomla 1.6 brought in several new features, one of which was 'Automatic update'. Because of the changes made in the databases during the various releases of 1.6 and 1.7 'Automatic updates' is best not used for Joomla versions below 1.6.5. Using 'Automatic updates' for 1.6.5, 1.6.6 and 1.7.0 has to be done twice to bring Joomla up to the current version.
