Since Joomla! 1.5.5 there is a built-in but not widely known component upgrade path. JoomlaPack installation ZIP is capable of using this functionality. All you have to do is merely install the new version without uninstalling the previous one. Honestly! That's all there is to it!
If you are using Joomla! versions prior to 1.5.5 there is no clear and concise way of upgrading components. In order to upgrade one has to deinstall the previous version and install the new one. This has one major shortcoming: the configuration is lost in the process as the table holding the configuration data file gets deleted like the rest of the JoomlaPack database tables.
In order to counter this significant shortcoming, we came up with the "configuration migration" feature of JoomlaPack. Using this feature you can take a backup of your entire configuration set (configuration options and all of the filters' settings) into an XML file, stored on your local computer. When you're done upgrading, you can use the same feature to upload the configuration backup file and regain all of your previous settings.

You can not directly upgrade from JoomlaPack 1.x to JoomlaPack 2.x. Before installing the new release you must uninstall JoomlaPack 1.x and make sure that all the jos_jp_* tables have been removed from the database. Failure to do so will result in inability to use the component. |
