OpenCSW and IPS on same Solaris 11 system?

Is there any danger running both IPS and OpenCSW side by side on a single Solaris 11 system? I assume there should be no conflicts since both package managers use different repositories and different installation paths and it would just add twice the updates since there are twice the package managers. However I just want to make sure since I come from a Red Hat background and I am a little bit cautious about having two package managers running side by side.
