A default PASOE folder that contains the WAR structure is added to the project. If you open 11.2.x, 11.3.x, or 11.4 workspace with OpenEdge 11.5 and if the workspace has any REST or Data Object projects, all the projects are automatically updated with the PASOEContent folder. If you open a 11.5 workspace, you can import the OpenEdge 11.2.x, 11.3.x, or 11.4 projects if the project type is either REST or Data Object, after import the projects are automatically updated with the PASOEContent folder.
