Is it possible to have a central repository supporting some users running VAJ 2 and other users running VAJ 3?
From a VisualAge 2.0 workspace, connect to your shared repository. Then import in the core VisualAge 3.0 projects (IBM Java Implementation, Sun PM class libraries, etc.) from the .DAT file on the VisualAge CD into your shared repository. Afterwards, you can install VisualAge 3.0 onto a new machine connected to the repository.
