To upgrade to Designer 4.0.1, follow the same procedure that is outlined in Section 1.2, Installing Designer. If you install Designer 4.0.1 in the same location as the earlier version of Designer you see the Designer Found message, asking if you want to upgrade. Select to delete the older version of Designer and install Designer 4.0.1 in its place.
When upgrading to Designer 4.0.1, take note of three items:
Do not use Designer 2.1x workspaces for Designer 3.0 and above. Designer stores projects and configuration information in a workspace and these are not compatible between Designer versions.
In Designer 4, default workspaces are stored under the %UserProfile%\designer_workspace directory for Windows XP, the %UserProfile%\designer_workspace directory for Windows Vista and Windows 7, and the $HOME/designer_workspace for Linux.
Import all Designer 2.1x projects into Designer 4.0.1. This runs the Project Converter Wizard, making the projects compatible with Designer 4.0.1. Be sure the option is selected. For more information on the Project Converter, see Section 18.1, Converting Earlier Projects.
If you are running workflow provisioning and provisioning with roles, follow the installation or upgrade procedures Migrating a 4.0 User Application Driver
in the Migrating to the Roles Based Provisiong Module Version 4.0.1.
