It is certainly possible to migrate from OpenJPA 1.2.x to 2.0.0. The exact
details will vary according to your dependencies, but I was able to migrate the
pom.xml file with a single version flag. I recommend running 'mvn
dependency:tree' and studying the results.
Here also are the OpenJPA sections of my pom.xml file. Perhaps it will help.
