I have to make some decisions about the joomla portals I have. Both are in 1.5 and new long term versions are coming.
The main reasons to migrate them are easy:
- Joomla 1.5 reaches its end of life in April 2012. After this point, no more security releases for Joomla 1.5 will be available.
- The new extensions are less and less developed on 1.5, and the extensions are from my point of view one of the Joomla key strengths, and I don’t want to loose this strengths.
So first step is to know the roadmap Joomla is going to take.
1.- This video is key to understand it: The interesting point is the explanation about how they are going to move from a release based lifecycle to a date based lifecycle (18 months for long term releases).
2.- This other link mentions other important things:
- Some kind of method will be available to move from 1.5 to 2.5
- Take care with 3rd party extensions containing lots of data.
3.- Features in Joomla! 2.5, here.
