There's been some confusion (and not enough communication from us) about platform support for Clearspace 2.5, so I wanted to post details about how it all works. In order to focus QA efforts we're phasing in support for additional application servers and databases throughout the 2.5.x release cycle. The most critical thing to know is that you shouldn't attempt to upgrade to 2.5.x until your environment is supported. Or even better, consider migrating to our recommended platform configuration (see below).


The table below represents our current roadmap for platform support (the release column indicates where a particular platform is first supported). As with any roadmap, it's subject to changes based on shifting demands or unexpected issues:
