There are some events on Mambo on September this year that Miro company has obvious intention to commercialize Mambo project and this made the core development angry. When all the communication failed, the core development decided to leave the current code base, and create a new project “Joomla“, based on the GPL Mambo 4.5.2.3.
As a loyal supproter for open source community, I managed to move my personal site from “mambo” to “joomla”.
The migration process is not difficult. Though there are some file permission problem, but it can be easily circumvented with my hacky scripts. Wysiwygpro has also been upgraded with this migration. No data is lost.
