In case you missed it, Software Product Compatibility Reports went live earlier this year. They are accessed from the IBM Support Portal via a link in the Support resources module, usually found on the right-hand side of the support portal home page.
These reports are intended as a compliment to the conformance
information currently published in Info Centers or, in the case of many
Business Analytics products, Techdocs. They cover the operating systems,
other software prerequisites, and virtualization environments that IBM
software products operate in, along with an end-of-service report
showing the actual or projected dates on which particular software will
no longer be supported. You can, for example, run the 'Matrix between
specific product(s) and desired operating systems' report to find out
which OS versions are supported for different versions of products. If
there is any discrepancy, the Software Environments pages should be the
considered the correct source.
