Migration from Oracle BPM exp files to Camunda

Hi. There is any tool or guideline to migrate from Oracle BPM to Camunda ?. I have some .exp files (a sort of zip file) containing several folders, each with some specific files like processes, componentCatalog, config ,etc.

Inspecting each file gave me more details and I cloud re-create same entities on Camunda but may be a time consuming and error prone task.
