Existing Installations
If you are not concerned about overwriting existing demo workflow process or life cycle templates, you can simply initiate "java wt.load.Demo " and answer "no" to all questions except "Change Management lifecycles and workflows" (see the Windchill Installation and Configuration Guide for further information about loading data). You can ignore errors regarding the "Change Items" Domain and the example projects. However, to avoid these errors, remove all sections from ChangeManagement.csv except those for the Change Management workflow process templates and life cycle templates.
If you do not want to overwrite the existing demo workflow process templates, PTC recommends that you perform one of the following options before loading the new workflow and life cycle templates:
Rename the existing workflow and life cycle templates using the Workflow Administrator and Life Cycle Administrator.
Rename the new workflow and life cycle templates by manually editing the ChangeManagement.csv file.
After loading the Release 5.1 workflow process and life cycle templates, you can restore them to their original state one at a time by clicking Delete Latest Iteration from the Workflow Administrator or Life Cycle Administrator page.
