Application Development Tools (ADT) /Program Development Manager (PDM) now fall under Websphere Development (WDS).
Hope this helps,
Although ADTS can still be used under support, ADM is intended to be replaced with Rational ClearCase. ADM might still work as long as a license is valid. If ADM remains at V5R2, the licensing shouldn’t change. The next biggest problem might be support. Although discontinued, support might also continue for whatever the contract terms were.
If you upgraded to V5R4, is ADM still working for you?
