When the Windchill 8.0 out-of-the-box Change Management workflows are run in Windchill 10.x, the user will see the activity variables in the task details page that are defined in the 8.0 workflow templates, instead of the activity variables that are defined in the 10.x workflow templates. Additionally, when running the Windchill 8.0 Change Management workflows, the user might see two Comment fields on the task details page; one for a defined activity variable and one for the Routing History table.
