Upgradation document from 3.0.1.1 to 4.0.7
One answer
The product documentation is here: https://jazz.net/library/#type=documentation&sort=pubDate
However, neither 3.0.1.x nor 4.0.7 are still supported. So the documentation for those versions does not seem to be available online any more. You might want to contact support, if they can provide an upgrade documentation.
