Hi All.

Creating a scheduled job which is supposed to migrate some data from one property to another (for two content types) in a controlled manner. 
For this I would like to create a project so its easier for the editor to see what has changed and can publish one item at the time, or everything if editor is happy with the changes.

The job is supposed to be a one time job, not to be run several times.

The job creates does the following:

1. Create a new project
2. Iterate through all active language branches
3. Go through every instance of BlockTypeX; make changes (e g migrate data from Property1 to Property2)
4. Add instance of BlockTypeX instance to project.
5. Save BlockTypeX instance with SaveAction
6. Go through every instance of PageTypeY; make changes (e g migrate data from Property1 to Property2)
7. Add instance of PageTypeY instance to project.
8. Save PageTypeY instance with SaveAction

We however get an error when adding instance to project when an instance of BlockTypeX instance is added to project when another language branch already has been added: "An item with same key has already been added."  So i guess language branch has to be referenced to the project item?!

The documentation is not helpful :D Seems its missing a lot regarding the programmic workflow  ;)
