ChiliProject is not maintained anymore. Please be advised that there will be no more updates.
We do not recommend that you setup new ChiliProject instances and we urge all existing users to migrate their data to a maintained system, e.g. Redmine. We will provide a migration script later. In the meantime, you can use the instructions by Christian Daehn.
Allow move wiki pages, versions, forums to other project (Feature #1179)
For different reasons I had to merge two projects in a single one. Both of them with wiki pages and versions.
I did't have problems with issues but I wasn't able to do anything with wiki pages, versions and forums,
I had to update that in the DB.
