If you copy a form template using another form target type and a custom action contains a condition that is not supported by the new form template's form target type, a warning message is displayed. If Remove Unsupported Configuration is selected, the unsupported condition is automatically removed when the form template is copied. If an unsupported condition is within a group, the entire group is removed if there is not another valid condition in the group.
Removing unsupported conditions using the Remove Unsupported Configuration option could cause custom actions to become invalid. If a custom action that contains an unsupported condition is still a valid custom action in the new form target type, the custom action is copied to the new form template without a condition. It is a best practice to review and test custom actions after unsupported conditions are removed before publishing the new form template copy.
