The project I am currently on is using Pentaho Data Integration (aka PDI or Kettle) to migrate data from Peoplesoft ERP (8.4 SP2) to Oracle eBusiness Suite (11.5). Notwithstanding the obvious absurdity of this move (I am a Peoplesoft person … so I am biased), the Pentaho ETL tool is proving to be truly excellent for the task at hand. Whilst the approach to this data migration is best described as “atypical”, the tool is at least making things easier than they might otherwise be.
I have used PDI on previous projects to migrate Peoplesoft data to Agresso Business World and to migrate Peoplesoft data to Peoplesoft itself – modified of course. Check out the Pentaho website for more details.
