BPM, Workflow, and Case

Hi community,

I want to retrieve annotations from a lower document version  and add them to a higher version in ibm fileNET P8 using java code.

In my process, I call up methods for writing on a PDF document, generating a new version of the document each time.
Before generating the new version, I wanted to retrieve the annotations from the current version and put them on the newly created one.

Need yours supports and tips.
