Relationships in Project Baselines

I am working with a project baseline that has been restored. I want to set the data date to the start of the project. This should had been done, but was not. The baseline contains relationships, so I expect activities to shift. How can I get rid of relationships in one shot to avoid this? Or are relationships important to maintain in the project baseline?

• Note in Oracle manual (which I do not entirely understand...I would need clarification!): When a baseline contains relationships to non-baseline projects, these relationships are maintained and copied when a baseline is restored. This could result in duplicate relationships if both projects in the original relationship are non-baseline projects. If one side of the relationship is from a baseline, no copy can take place.
