4.0.4 planning info different

we successfully clone a project from 3.0 to 3.0, including plans.
this same code looks fabulous on 4.0, duplicates the timelines, and plans.
(migrate ccm project into CLM project)
but none of the plans will open, with error
backlog iteration /development/backlog does not exist
yeh.. its not visible on the 4.0.4 server in the source project.

Accepted answer

In the Plan configuration you have to select the correct Iteration as backlog.
The /development/backlog was the one that was configured as part of project creation.
You can update this value from Project area Editor of Eclipse client --> Process Configuration tab.
In the tree select Project Configuration --> Configuration Data --> Planning --> General.

fabulous.. thx.
no iterations were created at project create time.. my utility cloned from the other project on another server..

neither of the servers projects had an iteration selected as the backlog iteration.
I selected one, and the plans work now. the project area didn't asked to be save however when I made the selection as I would have expected.
